Liquid Nitrogen Dewar

Recommended Posts

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,

How small is small?

The ones they sell for people who want hot coffee while hill-walking are actually pretty good.

We always used to use polystyrene buckets for small short ish term storage and use.

We had our own manufacturing plant (mostly for the liquid helium) so don't know about that, sorry.

One has to be a bit careful though. If one seals them tightly, they might shatter.

A loose, makeshift bung made from cork or polystyrene should resolve that I reckon.

That is what many use. One should also make sure that the inner lining can survive the temp shift.
