zarnold16 0 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 0 Share this post Link to post Share on other sites
John Cuthber 3814 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. 0 Share this post Link to post Share on other sites
Klaynos 739 Posted January 26, 2017 We always used to use polystyrene buckets for small short ish term storage and use. 0 Share this post Link to post Share on other sites
zarnold16 0 Posted January 27, 2017 I was under the impression that you needed a dewar to get LN2 from a industrial supply company. 0 Share this post Link to post Share on other sites
Klaynos 739 Posted January 27, 2017 We had our own manufacturing plant (mostly for the liquid helium) so don't know about that, sorry. 0 Share this post Link to post Share on other sites

DrP 591 Posted February 1, 2017 A loose, makeshift bung made from cork or polystyrene should resolve that I reckon. 0 Share this post Link to post Share on other sites
CharonY 2384 Posted February 1, 2017 That is what many use. One should also make sure that the inner lining can survive the temp shift. 0 Share this post Link to post Share on other sites
