zarnold16 Posted January 26, 2017 Share Posted January 26, 2017 I am currently trying to find a cheap liquid nitrogen dewar to do some experiments with. Where would be the cheapest place to get a small dewar? I am located in Michigan if prices are region based and where to get them. Thanks, zarnold16 Link to comment Share on other sites More sharing options...
John Cuthber Posted January 26, 2017 Share Posted January 26, 2017 How small is small? The ones they sell for people who want hot coffee while hill-walking are actually pretty good. Link to comment Share on other sites More sharing options...
Klaynos Posted January 26, 2017 Share Posted January 26, 2017 We always used to use polystyrene buckets for small short ish term storage and use. Link to comment Share on other sites More sharing options...
zarnold16 Posted January 27, 2017 Author Share Posted January 27, 2017 I was under the impression that you needed a dewar to get LN2 from a industrial supply company. Link to comment Share on other sites More sharing options...
Klaynos Posted January 27, 2017 Share Posted January 27, 2017 We had our own manufacturing plant (mostly for the liquid helium) so don't know about that, sorry. Link to comment Share on other sites More sharing options...

One has to be a bit careful though. If one seals them tightly, they might shatter. 1 Link to comment Share on other sites More sharing options...
DrP Posted February 1, 2017 Share Posted February 1, 2017 A loose, makeshift bung made from cork or polystyrene should resolve that I reckon. Link to comment Share on other sites More sharing options...
CharonY Posted February 1, 2017 Share Posted February 1, 2017 That is what many use. One should also make sure that the inner lining can survive the temp shift. Link to comment Share on other sites More sharing options...
