What are the costs of ln2

[VeeDub]

Whats up lads, Ive been reading about Ln2 setups for a while and have been bitten by the bug, I'll have to put out some benches with it, I was just wondering how expensive it is? I don't even know if I can get some yet, Im in Ireland, did a couple of google searches couldnt find any sources yet

Any advice greatly appreciated
VeeDuB.:D

[HawainPanda]

easiest place , well at least for me cus i work there is at any hospital, they use ln for lots of things, remove warts...store cells( and sometimes sperm, like in one lab i volunteer for)
the bill is 15.6 for 30 liters, so .52cents for 1 liter these are in U.S. dollars
cheaper than soda!!
oh..and u can get dry ice for free(if u ask around) or i could get some if u lived in tucson, but the labs don't always have them

[charlie]

'yer lucky!!! LN2 is $4USD per liter here!

C

[skate2snow]

And me its 14CND per litre!!!

[bh2k]

1.50 a liter.

[lupacchiotto]

thanks for the info...
it can do!

[Unseen]

how much does it cost the can? I think this is the most expensive part not the liquid.. Here in hellas i take ln2 for 3 euros per litre.

The can i found for 12lt costs 480 euros...

[HawainPanda]

lol, yeah, i think so too..the cans are heavy as hell, although there is a small 3 liter bottle they have lying around bleh, im sure u can just use some dense styofoam box (ithink)

[SLN]

I don't think dense styrofoam works...
I am a chemist and we use LN2 (along with ethanol) almost daily for our -100 reactions. The containers you are looking for are called "dewar's" and as unseen said they are pretty expensive. You can however use a very good quality thermos (which is what we use to transfer small quantities of LN2 from the large 10Lt dewar to the thermos and then on to the reaction. Be advised that this will sooner or later break your thermos nomatter how good/expensive it is. We have found that thermos with "glass/mirror-ish" inside walls last longer than those with plastic insides but I stress this again : They will all break eventually. I had one of those mirrory thing break in my hands while I was pouring LN2 the other day. They go out with a bang! The inside was shattered but the outside held up! Very cool! :D
Once I upgrade to A64 I might put my sig system through LN2
I recently heard that maybe grounding is reguired through the serial ports to avoid superconducting phenomenae that might occur in the mobo at -50 Celsius. Any truth on that?

[saaya]

interesting info about the termos! thx for sharing :toast:

afaik the bios chip freaks out at too low temps, thats you gotta watch out for i think.

well and the cpus dont like too low temps, but its nt that easy to get THAT low temps anyways.

[HawainPanda]

oh yeah...the drewar, lol, i just read that in my physics book..dang..i think i was referring to di for foam..bleh im clueless rite now

[!!etomac!!]

is dry ice more expensive thn liquid nitrogen
because there r more N2 in the atmosphere compare to CO2
but there are many carbon atoms in the world (anything organic.)

[sang]

....52cents for 1 liter these are in U.S. dollars
cheaper than soda!!
..

heh,here its $0.30 per liter.And soda its not cheaper...but there's always the beer !! :D

[KickerZ]

sweet now i finally got to see what the inside of the tube looks like im gunna totally make one of these been wanting to for soooo long wanna try dry ice and then im gunna have my neighbor bring me home some LN2 from his work, he works for liqued air or airgas or what ever its called and this is my first post here yay :D and hawainpanda if i start getting into this ln2 cooling im coming down to tucsan to pick you up :D :p: i live in gilbert :banana:

[detonator]

Italy 0.80Cent of Euro per liter,so around 1$.but the dewar is so dam exspancive....

[TheTrebleKing]

Here (http://www.keison.co.uk/acatalog/Catalogue_Index_Dewars_in_Stainless_Steel_Containe rs_16.html) you can get Dewar flasks in the UK, quite expensive though.

[Vandread]

So what would this cost?

:slobber:

[total_assault]

I would think phase-change would be less expensive lol

[SLN]

Οk here's the deal....
If you want to take LN2 and not to use it immediately, (excess of 8 hours) you have to go for a high quality container. The best you can take is cans that have a vacuum wall. heat transfer is minimal in a vacuum (actually it's zero, but you can guess that the vacuum achieved in the wall is never that good to assure zero heat transfer). So after that you need to tackle the issue of N2 evaporating and taking air form. It has to be released somehow because otherwise it would create tremendous pressure in the can. So the extremely high quality containers have a closed cirquit with an exhaust valve that takes the air nitrogen, takes it through some traps and loops and manages to re-liquidize it and add it in the can again thus managing close-to-zero LN2 loss.

[Lowvez]

if you are a student at my university you can take what you need for free...same with dry ice...

[d3birth]

And where would this university be located?

[G H Z]

Outside of the inside track that some people have, where can this stuff be had in the US, and do they rent dewars?

[G H Z]

Well I found some locally.

http://www.praxair.com/

They said LN2 is not controlled, anyone can buy it. The only restriction is having a DOT approved dewar for transport.

About $3.75 per Litre.

[Jort]

here its 25L for 37€

air liquide:)

[Rub87]

Hmm, I was wondring, if you put a big cilinder on your little cpu, pour it full with LN2 and connect a big vacuumed cilinder with it, this wouldn't this cause even colder temps for a very short period?

There is a company near Gent that also makes all that kind'a stuff, they supplie tha NASA and stuff, a friend of a friend works there. But the ideal combo would be: doctor + oc'er. So you'll earn plenty of money to buy those expensiva hw and you need a high quality dewar and LN2 to remove warts and stuff :D

For a VERY SHORT period of time, yes. However, fairly quickly it would fill up with the N2 that vaporizes and get up to high pressure, possibly resulting in an explosion.

[GoriLLakoS]

Here (Greece-Athens)...is 2euros/2.64usd per Litre...!

But i found someone who can rent me a can with 25L for five days for 30euros/40usd only....
woot

[harleybro]

Please pardon my lack of knowledge in this area, but is it safe for me to assume that LN2 can be purchased by anyone without any type of certification or license? I can just drive up to the Praxair facility in Long Beach with my DOT-approved Dewar and $40.00 and then drive off and be a happy camper? If this is the case, then I'm seriously going to shop for a dewar. :D
Correct from what I have found no certs. needed. You can go to most gas suppliers to purchase it. I personally am working with Wilson Products. Also you can call and possibley rent a dewar since purchasing them is so expensive. :) I had found a 30day 180L rental for $30.

[G H Z]

At the location I inquired with, they said there are no dewar rentals. Too many broken one's apparently. What they should do is have an appropriate deposit taken with a rental so that whoever recieves the rental knows they will have to pay for it if they do break it.

My next task is to contact a few Dermatologists in the area to see if they can help me track down a used dewar, or perhaps borrow an old unused one.

[Jort]

i think thats the most common way, brake it is pay it.

conrad.maranan i found i also very strange that they give the ln² to anybody.
but hey i am not complaining, have to find a dewar too.
asked a prize of it and when i know i'll share it:)
its the left one in my ava, its 11L(maybe a bit too small but refill is not to far away from here:))

[gocchin]

There's a praxair depot 15 minutes from my house... I just called them and they can supply me with both dry ice and ln2 w/ container rental (pay as you go)... looks like bye bye vapochill, hello ice and gas...:)

Now if only I can figure out how to handle ln2....

[Lowvez]

And where would this university be located?

Dalhousie University, Halifax, Nova Scotia, Canada.

You have to be a student in the physics department.

[wdrzal]

A lot of the dewars that I have been checking out in the last few days do not indicate anything regarding DOT-approval. This one (http://cryodewars.com/catalog/product_info.php?cPath=34&products_id=31&osCsid=5dff32eb59df86136bae93bb07feacd7) is a bit pricey but seems to be a good size for me. There are others on ebay, but I'm not too sure about the quality.

Those are lab dewers and not for transport, in the usa you need a dot approved dewer to transport unless you walk home !!!

[harleybro]

Rental for tank $30 a month. 180L of LN2 for $125. Stainless thermos for transporting from tank outside to rig inside $20. :)

[harleybro]

In the USA 90% of buisnesses could care less about the department of transportation, HEHE.
Agreed but for instance the field I work in HVAC and the area NJ dot is a big problem. Bridges going over into NY are very strict about what is carried on vans and such. I believe you would recieve a pretty hefty fine in using non-dot containers. :)

[...:::MadDog:::]

Hy there,

Can someone tell me if Airliquide rent the dewar's ?

Its great if they to that :D

its 1985 that he says that.

and how long does LN2 last? by last, i mean like how long in your computer.

[marvt74]

Depends what your cooling on average its around a litre every 10mins is used

[viper650]

oh ok, nevermind. i thought it would last a while... didnt think it would go that fast, ill stick to my water. much much cheaper(and affordable for me)

[marvt74]

Aye its never meant to be a continuous usage thing, just for benching the life out of any hardware for a short period of time to push the limits

Don't you have air liquid there???:)

[Vegitto]

Okay, for the people over in Holland: Are you allowed to buy/posses LN2 when a minority?

[ObsesivComplsiv]

Hey guys I was browsin' along and saw that some of you are having a hard finding a hook-up for ln2. I work in the dairy industry and most breeding nowadays is done via artificial insemination. The units of semen are store in ln2 until they are used. So if there is a dairy or horse ranch in your vicinity even if they breed the "old fasioned way" you can bet they still have a salesman that comes by from time to time trying to talk them into changing there mind. Anyways, the point is the dairyman usually gets his ln2 delivered to him free of charge and probably has grip tanks sitting around that the salesman comes by to either swap him for full ones, or to refill them with the 300 gal. tank he's that pulling behind his pickup. He buys in bulk and will give you twice what you could get at Praxair for same $$$ and maybe even throw in a tank! Worth a shot.
Giddy up! :)

[Dumo]

Most all LN2 dewars @ ebay sold to either breeders or overclockers:)

[Victorshen]

LN2 here in Syd, Aus is about AUD 3-3.5 per litre, also any buddy to gimme somt tips buying a dewar? like 2nd hand one on ebay, coz i have no idea what to check b4 buying

Just thought I'd mention that I've taken a look into ln2 for something else, but from what I found apparently it's sometimes used in Welding projects. If you're still having trouble finding liquid nitrogen, try looking in places that carry welding supplies.

LOL that is hilarious in so many ways.
LN2 isn't about wanting to do dangerous stuff, it's about doing your research and use it properly.
You don't get anywhere with risking your life in overclocking.
In skating you might, but in overclocking research and using your brains and not your gut is everything.

[prosk8]

i love to take a risk
some one ho can to give a link of a shop ho sell ln2 and dice
please

[M.Beier]

First of all, your probaly not old enough to purchase LN2, second, your sure as hell not wise enough to use it.. - No LN2 for you untill you get more wise....

And stop askin' ppl in here are responsible and it would be highly unlikely that anybody will get some for ya.. And hell no you wouldnt get it in Europe.. One has to be 18..

[prosk8]

Im 25

funniest post ever.

seriously though man, you have to stop this.

it sounds like you want to be stupid and dangerous with the stuff. and i dont think XS wants to be associated with your death/injuries you might get if you get some LN2.

dont get yourself banned for being so foolish and dangerous. nobody here wants people getting hurt.

Any tips where to find LN2 in Atlanta/GA ? :confused:
And where can i buy a good dewar ?
Can't find any place and i've been trying for a long time now :(


$2.00 a liter here in southeast US

Like where ? :)

[G H Z]

If you have a commercial location (they will not deliver residential) you can setup an account with one of the retailers like praxiar and get a better price. In Seattle with an account you can get 180L for around $125, otherwise you pay $3 per litre and have to pick it up on your own with a DOT approved dewar in the back of a pickup or similar. They don't let you take it in cars, at least not here.

Thanks a lot for the tips G H Z :toast: Looks like i found a few praxair locations in my area , now i need to find a place that sells DOT approved dewars i guess :D


in the back of a pickup or similar wonder if i can put it in the back of my Honda Passport (isuzu rodeo) in the cargo area :rolleyes: :) ...

[G H Z]

Maybe, the idea is they don't want it inside the passenger compartment sharing the same air space, I guess they don't want you becoming asphyixiated while driving. They are very strict here, we've seen lot's of pics of guys with it riding shotgun in a coupe but that's not happening here in Seattle. I can open a window you know ;)

I'd check eBay, there's usually a few on there to look at.

[BNDMOD]

Hey anyone kwon where i can get LN2 here in Argentina?
Thanks

[socket]

it is very low cost, but i need liquid nitrogen in slovakia or czech.

[BNDMOD]

Anyone know???

[Bigchrome]

If people are having trouble finding it in Ireland BOC gas seems to be the best place. It's €90 per month for 200L tank rental + filling. For dry ICE Munster CO2 is 1.50 per kg very easy to deal with and collect. I see a lot of noobs here over 18 too. You're all way too old:p:

[wdrzal]

Age has nothing to do with being a noob..........intellagance does,.....guys come here to learn ,but if you haven't developed the ability to research the regulations in handling LN2 and finding a place to purchase it,I'm afraid your going to be a noob a while longer , until you do.

Its NOT about keeping secretes, but since almost everyone is anonymous and their profile is made-up or exaggerated by quit a few,we can only judge your ability, by how intelligent your questions are .

PS: This site is full of info if you read more than todays posts. read stickies and threads in area of interest.

I was joking.... Then again with an IQ of 140 I don't exactly lose on the intelligence side either.

$3 per liter here in New Mexico.

[bluep3ace]

its getting pretty close to summer now, and its nearly 90 degrees here in massachusetts.
are there any uses for LN2 for cooling a room? (putting it in front of a fan, etc?)

[Brettbeck]

Not really. It would be way too expensive and most of all very dangerous.

Get a good A/C system and you will love it! It will save you so much time, effort and money.

do as Brett said,Buy a AC unit for 100.00 boiling off enough to cool a closed room can cause asphyxiation and be cost prohibitive because it will displace oxygen,you first pass out then if o2 gets low enough your dead, or a vegetable.

Same up here Gorod, it's real easy to burn thru cash with this stuff ;)

Yah ... i was hoping it will be like $2 or close to it :rolleyes: . With those crazy prices i wont be able to bench frequently , maybe once a month at most :( with LN2 , with DI it's 5 times cheaper (1$ / Lb , 20 Lbs enough for 8-10 hours , 25L LN2 i guess about the same 6 - 8 hours ? :shrug: )

[Planet]

I was looking at 100 to fill a 160 liter. Plus 50 for a monthly rental.

[Stapler]

Hey do you know which types of air gas stores carry LN2? Do the regular branch stores or do they have to be retail stores?

[Brettbeck]

Is it legal to transport LN2 in your own car in the USA?

Here in the UK it costs about £80 IIRC to fill a 25 litre dewar and £50/month rental.

Larger quantities are much cheaper... that 800 litre dewar in my avatar is 40p a litre IIRC (£0.40). The company who owns it said if I had my own dewar they could fill it for me :D.

[Jaan]

Larger quantities are much cheaper... that 800 litre dewar in my avatar is 40p a litre IIRC (£0.40). The company who owns it said if I had my own dewar they could fill it for me :D.
Yes, one biger company here pay under 400$ for 1000L. Thankfully I have a good frend there, so I have 2x16L LN2 in month for free :)
If I want more LN2, I have to bay from local gas retailer AGA- usualy I pay 22$ for 10L, but they always fill my dewar full somehow :D
DI cost under 15$/10kg in AGA, but my frend support me in this part too for free ;)
I have my own 16L dewar and 15kg DI box- purchase/carring/preservation is a lot easyer this way.

[Stapler]

In central PA it's $2 for a litre of LN2 and $2 for a pound of Dry Ice.

[Gautam]

You gotta look harder Stapler, I'm 1/2 1/2 that. ;)

[Stapler]

For which, or both more likely:(

I'm sure in CA I could get it cheaper, but in PA I've only got one airgas near me, so it's $2. My benching rig is in PA, no benching in CA, so I'm stuck. It's ok, I can only bench when I'm home from boarding school, so that means summer and a few breaks so $2 isn't going to kill me.

[Nordling]

20$\26l Ln2 :(

[Nordling]

and 0,5$\1kg Dry Ice

[Gautam]

20$\26l Ln2 :(

In the grand scheme of things that's pretty good.


I get mine from an Airgas store as well. Problem is they all operate seperately. Shop and call around and you might find one with a nice selling price.

Unfortunately no matter how you slice it LN2 is much pricier to bench with than DI.

[Stapler]

^It's worth it to me though. My chip is just about at the absolute limit of what dry ice can do, and I'm not satisfied. 4975mhz dry ice doesn't leave me any room for improvement, so LN2 is a must. Unless I've got a real low FSB wall, I don't think 5400mhz is overly optimistic for this chip, and with P35 and 5:6 that'll give some good times I think.

[shimmishim]

glad i found this thread (dunno how i missed it).

i will see how much LN2 is at Praxair and Airgas which are both in Knoxville. :)

Dry ice is $0.42/lb in Knoxville and you can also find it for $0.22/lb in Loudon which is about 20-30 minutes away. :D

[harleybro]

I use airgas for LN2 I rent a 160l dewar for about $35 a month. Filling the dewar is $94/160L. Dice runs me almost $2 a lb. :(

[[XC] Luckygriff]

Guess im lucky here to cause I have access to a shop that repairs truck tankers and guess what rolled in. A praxair tanker with over 180 L of ln2 in it. All free. Ah thats some fun times. There co2 truck are cool to the pipe on back when emptying it get sub 80's frosty :)

I use airgas for LN2 I rent a 160l dewar for about $35 a month. Filling the dewar is $94/160L. Dice runs me almost $2 a lb. :(harley, where in NJ are you getting your LN2 and dry ice?

[harleybro]

harley, where in NJ are you getting your LN2 and dry ice?

Actually I am Hunterdon area and airgas in Easton PA delivers. I normally get the delivery the day after they call. I keep forgetting I am supposed to call the rep if I use enough they may discount further. The dice is from Wilson products again in Easton.

Wierd, I was quoted less than a buck per litre I think... of course, if I took the whole damn 200 litre... not sure what I can do with that if I do...
Maybe have LN party at my house? don't really have enough space for too many people with garage filled with equipments... -_-;

[pReya]

Just ordered some LN2 in Germany at Linde. 4€ / litre, taht's quite expensive. But i can borrow their Dewar for free for one weekend.

[s0lid]

How long u can play with 10l?
4-5h sounds good cuz i don't really have much time to play with ln2 or DI...
I need to ask from AGA how much ln2 costs in here finland...

[s0lid]

Omg ln2 costs here over 9?/litre...
Sorry for douple post cuz opera mini can't edit posts...

[kiwi]

Sorry to bump old topic :D

Yes, AGA sells LN2, their price is $3/L in my banana republic :D I can get it cheaper though from other places - like $1.5/L, so 20L dewar is $30

[tiborrr]

Here it is around 30EUR for 0-39Litre refill at Messer. Havent asked for greater quantities.

[bf2142lol]

[DRCRAWFISH]

:D I see in Poland we have cheap LN2 (God water :cool:)

40 euro - 30L LN2
25 euro - commuting track with LN2 to my home.
2 euro per day - dewar rent.

[ceemic]

Yesterday I got my own 20L dewar: http://ceemic.pri.ee/hardware/termos/ :cool:
Today I went searching to buy LN2. AGA sells it 2,5$/1,6€ for litre; but I got "inside" info, where I could buy it 1,0$/0,6€ litre :D Its in a "breeding centre" :ROTF: And if I lie them, that I breed animals my own, I could get LN2 for 0,6$/0,4€ per litre :yepp:
For instance, DICE costs ~1,7$/1,1€ kg...

[yiancar]

how much u bought the dewar?

[ceemic]

yiancar, 50$/32€ :)

[yiancar]

OMG this is extreamly cheep

in Cyprus where i leave to buy a new one is about 3000 eur :P

[ceemic]

yiancar, yep, I know. Here in Estonia, the new ones are also 3000+$/€. My 20L is from the "good old" CCCP times. It's made in 1979 :D

[yiancar]

you are very lucky then , every time i use ln i have to take an old dewar with no vacuum and it cant hold the ln for more than 24 hour no 20 :p

[ceemic]

yiancar, I haven't used my dewar yet. I hope, it's working fine...

[yiancar]

i hope too :)

you are very lucky then , every time i use ln i have to take an old dewar with no vacuum and it cant hold the ln for more than 24 hour no 20 :p

[yiancar]

:D on 17th i will try to have a season ( 10 hours ) with blackops , i will take u a pic then :P

+ no pressure which means you have to transfer the ln from the dewar to the thermos like milk to the cap , so u need 3 people :D

[warmaster]

Serbia, 1.5 euro per liter...

[stangracin2]

can we make a total price list

[ceemic]

I just bought another 20L LN2 from "animal breeding centre" :D This time 0,6$/0,38€ per litre :cool:

[blind_ripper]

price's have gone up in belguim for LN2 , its 3.52€/L ln2. filled 50L last mounth cost me 166€ :(

[Viss]

I pay €2,- for a liter if i pick it up approx 30km from my place. Delivered its €1,30/L however they charge 65,- for the delivery itself so thats no good with only a 30L dewar :D

[BenchZowner]

OMG ceemic with those prices man!
Damn, I wish I could pee LN2 :p:

Last time I got my dewars filled here cost me ~2.5$/2.1euros per lt

[thunder_2008]

Seems to me as if making that for the amount of money it's going to cost that skiping dice for ln2 is the ticket. So far I know that i'm goin to need alot of insulation for mb vgas'...i'd like to have two or 4 depending upon what design for my 3870x2s' then a nice pot for cpu...not sure if I would want one on n/b as I might opt for putting LS...ahh...2nd thought ...pot on n/b too. Then a dewar...with pressure valve...then probes for all the pots...at least one temperature reader that can read 4 or more temps simultaneously....and or 4 separate lcds....whosh...that's alot of dough already.

This is my ? how much is a this stuff:

1-F1 cpu pot

2-tek-9 4.0 need 4 of them...yekkss

3-Taylor Wharton LD50 dewar with pressure valve setup

4-insulation supplies

5- 3xtemp probes & lcds' readouts

6-juice for the ld50

7-anything else I did not mention

Please guys I'm curious to try ln2...and so I want to know everything about as much before hand.

I am just guessing here, but your talking about some major cash to get all that one go.

Bran new the LD50 wil be ~$2,000+. A LD25 with stand, pressure top was like ~$1,500 here. Best bet is to just hang out on ebay and look for em there, or try and find used ones around. To fill a LD50 in my town, costs normal buyers ~$125ish maybe a bit more. Not telling my costs :)

Ask Vince about the pots or look around for used ones. Thats about another ~$2,000 for all that stuff.

The rest of the supplies are nothing compared to the costs of Pots and Dewars.

Just collect your stuff slowly and get it when you can find the right prices, new or used.

[[XC] gomeler]

Call blackhole for a 25L dewar, costs $180 shipped. Talk to AirGas about either having a 180L dewar delivered or storing a 180L dewar at their local facility and filling off it yourself. This will drop your LN2 costs by half. Then go either search for a used LN2 pot or buy one from a notable seller. My entire LN2 setup cost me $700 with $160 deliveries of 180L dewars to my house. Much cheaper than $2000 ;)

[Oliver]

having 180L would be awesome, i saw your dewar Gom quite cool :)

try get 180L into my room in first floor department haha, imagine that man

[Buckeye]

Oh yeah I forgot about blackhole :up:

Yup bran new those Dewars are just over the top costly.

What do they charge you for a depost on the 180L ?

I got a taylor wharton 50LD from the black hole for an outrageously good price. I had to sweet talk them for a while though. THey said no more at that price (I was gonna buy a few and throw em on ebay) too bad :(

btw... $240 shipped LMAO! talk about deal of the century

My setup other than the dewar is

2x copper/alu gpu pots
copper/alu cpu pot
copper/alu northbridge pot
(all made by duniek - who I highly recommend for a first time setup)

Fluke 51S digi therm
Some chinese brand digi therm 2 inputs (cant read chinese so I dunno what brand it is)

My total setup was about $700.

Cost to fill my 50LD is $80 or $1.60/liter.

I goto a welding supply shop (they have dry ice too cheap $.50/lb), guys think im crazy using the stuff to cool a computer. they always ask me what I blew up this time...

The prices depend on the consumption.
The more LN2 you buy from the supplier, the better your price gets.

I'm quite sure that you're buying at least double the quantity Deux buys monthly.

[GraduS]

10$/35l :D

[sofos1990]

In Greece we buy it for 1.45/L, but some guys in Crete(they have some contacts) can buy it for 0.90/L :D

[Alexxx650]

$300 for LN2
$29.95 delivery charge
$400 depost for the Dewar
Some other hazzard material charge.

The are charging me $125 to fill the 50L Dewar I have now which lasts me about a weekend.

$100 for LN2
$25 hazzard material charge

Nothing like dropping $125 and watching go up is Mist/Fog and Ice.

About 0,6$ US/litre here in HCM city - Vietnam. Whether you buy it much or less, the price will not change.

In North FRance/South Belgium

50 liters : 125 Euro (175$)

400 liters : 450 euro (630 $)

On average,legaly, it's about 3$/l

[proxis]

ln2 is very cheap in the Eastern Europe ;)

[ceemic]

proxis, actually, its not the case. All the LN2 comes from Finland (AGA/Linde Gas) and the original "end-user" price is 1,6+€/2,2+$ per litre. The cheaper "source" is in animal breeding centre, because the "Department of Agriculture" is dotating it.
But the most important thing is, these resellers are making money to themselves "illegally". The few guys here in Estonia are buying so little LN2 that it covers the "normal" loss of LN2. So the sellers can put the cash to their "pocket" - simple as that.

PS, Estonia is Northern Europe ;)

$1.00 a litre here in middle TN...you need to be wheeling and dealing with Airgas up there. The main facility for the South East is located in Chattanooga iirc.

[aditya]

$0.90/L here in india, regardless of quantity :)

[biglipzit]

$0.50 a liter here in Omaha from praxair when buying 160L's and less if you buy larger quantities...

[TheGoat Eater]

since I can't fget delivery into the suburbs here in Des Moines I am stuck with $1 litre to start and then it will go down from there, oddly enough Praxair are Delta Bravos here and said they wouldn't sell to me and Airgas is like freaking expensive... the local shop took time to listen to me and get an idea of what I was doing and offered a good price that would go down with quantity. still bummed no delivery so I may just get ti delivered to our downtown store's fallout shelter :D

[MTP04]

The more I buy the cheaper it gets but I still think its a bit over priced.

$75 for 50L or $240 for 180L. Dewar rental included in the price.

Welcome to "Bananarepublic of Estonia" :D

[bartx]

Some prices are really hard to understand - I've got in my town Linde Gas factory, which sells ln2 for 3$/l but I can buy the same ln2 for 0,6$/l (small company which is buying it from Linde). But if I don't have own dewar I can't buy it anywhere :shrug: Generally Linde has the biggest prices for everything. They have refrigerants almost two times more expensive than can be bought in other companies. Price of dice is also sick - 3$/kg (rose 3 times during this year).

[tiborrr]

New prices at Messer are 1.0€/L + tax, which makes for a total of 1.2€/L in Slovenia.

what size dewar would i need if i want to bench for 1-2hrs?

[ceemic]

what size dewar would i need if i want to bench for 1-2hrs?
Depends on what CPU/VGA You want to cool. But 5L to be sure. Tho, these 5-10L dewars are usually not so good as 15-20L. If You find a good 20L dewar, it would be a good staring point. Good dewar has little LN2 loss and You can have another run weeks after You fill it up.

Around how much would a good 15-20l dewar cost?
what should I look for in a dewar?

[ceemic]

Assassin48, I have no idea about prices there in US. I got one very good 20L for some beers. And two 20L for ~75$. Two of them holds LN2 over month. Tho, they are old USSR ones, but still good.

If You don't want to buy a dispenser top, then You have to look, if it's easy to pour LN2. It has to be light also. I have seen 30L steel dewars and they have extreme weight :D
The "mouth" of dewar shouldn't be too big and not too thin also. Normal dewars have ~2-4'' diameter mouth.

[Assassin48]

what you think of this one?
it doesnt have the dispenser
its going for $225 shipped

Hi,

There is an Airgas right next to me (Airgas West Facility Type(s): Branch
Medical Branch) and I'm planning to do my first LN2 purchase soon.

What should I expect? Are there any requirements (min. amount, special handling permit, etc)?

Can I just arrive there with a dewar and ask them to fill it up?

Can we use conventional thermal bottles to store LN2 for a day? (http://www.amazon.com/Sigg-Thermal-Bottle-1-0-Liters-Anthracite/dp/B000R7JJLW/ref=sr_1_3?ie=UTF8&s=sporting-goods&qid=1257869306&sr=1-3-spell)

Can we use conventional thermal bottles to store LN2 for a day? (http://www.amazon.com/Sigg-Thermal-Bottle-1-0-Liters-Anthracite/dp/B000R7JJLW/ref=sr_1_3?ie=UTF8&s=sporting-goods&qid=1257869306&sr=1-3-spell)

Thanks!

I suppose you can use conventional thermal bottles for a day, but then for 20/30 liters you'd have to buy 20 / 30 thermal bottles ( we dont have em bigger then 1L, atleast, i havent found em yet ) and they cost quite some aswell. proper 2ndhand dewar on ebay is the best way to go i think.

Thanks, yeah I got a small cryogenic container (2l) that will do for quick sessions. I have an Airgas 2 miles from my place so it will be easy to get more.

I'm looking for a 10-20l used dewar and a decent Ln2 Cpu_Pot now.

I'm almost set with a bartx 1600g cpupot but can't find any reviews on it.

Since most places require you to use a truck to haul the dewar home (i have a van and station wagon), i'm planning on going through a company i used to work with when i did HVAC because they'll drop it off at my house or let me take it home in my van, whereas no one else will do that for me due to insurance reasons. However they are telling me i need some sort of certification on my dewar (i guess aside from DOT) to make sure it's still in proper working order. They also haven't told me where to go to do it. I assumed the gas company would do the testing.. The company that's given me the lowest quote so far (125$ for 80L) looked at pics of my dewar and said it's cool, they just need to hold it for 24 hours to do a cool down (something i thought they only did for LHe, but my dewar has been in storage for at least a year, and still holds some degree of fluid according to meter no biggie) and then i can pick it up the next day full, if i had a truck. Any of you have any idea what they are talking about for certification? Isn't that testing done by suppliers? I have a tank of co2 for my MIG and i can pressure test the thing, though i know it doesn't leak because i can open the discharge valve and hear gas escaping... i guess that doesn't tell me if it can take the 12psi the tank operates at.. Nitrogen would probably be a better alternative for pressure testing though, wouldn't it? Dewar can be seen in my sig.

Mine has a DOT tag on it. I am not sure what they are talking about a cool down, your Dewar is not that much bigger than mine at 50L.

Yes they do cool downs on LHe Dewars but not really necessory on the size Dewars we use.

Reason they might want to do a cool down is so they do not waste so much LN2 to start filling it up, a fair amount can used in this process I guess.

Well they pick it up and return ir for you ?
I know airgas will if you have your own Dewars, the big ones that is.

I guess, worst case, just send it over to me and I will take it off your hands ;)

First, it's either source are small regional (by region i mean northern illinois) places so they probably don't want to lose any more gas than necessary, and probably make sure it holds pressure. I don't know if the other source would want to do that as well.
No, they won't drop it to a residential (haven't asked airgas, as they are little bit more than twice as expensive) but you just made me realize hey, i have a commercial address i can get it sent to and then take it home from there, since they will not let me do it without a truck for insurance reasons where as the place i'd have it delivered carries no responsibility for me dying in a freak ln2 leak on the 15 minute ride home. (on a side note when i worked at the tollway an airgas or praxair truck filled with some gas, and it must have a pressure release system incase of emergency, and it was venting, at about the volume (dB) of a commercial jet taking off.:yepp:)

Your dewar might not be that much smaller, but i do recall mine weighing ~270lbs when full of LN2 so even once i get it home getting it out of the vehicle will be fun, and i'm not even sure the proper method of lifting when full, i do recall it saying not to use the handles... i think a ramp still.. Any big guys in chicagoland want to bench with some ln2 and an otternase pot, just gotta help me get the SOB out of a van :rofl:

Despite the really complex manifold on my dewar it does still have a gravity feed port, and it came with a 36" or so hose so if i rent i can transfer pretty easy, can do it with almost no lose if i can find an adapter..

0.9$/L in Hanoi, Vietnam :D

$70 plus tax to fill a 35L dewar. or 2.50 a liter.
