In my area they are not allowed to deliver to residential areas. I have spoken with them and they have a 30l they loan out however they were unsure where it was or what customer had it. I plan on calling them again to see if they located the dewar. One of my biggest issues is the big temp swings with the dry ice. If I could hold a tighter temp range I think I could get even higher.
