Foam Cryo Dewars - Small Vessel

The preferred containers for handling liquid nitrogen and cryogenic materials

These foam dewars are safe, durable, and have superior insulating properties compared to stainless or glass, at a fraction of the cost!

Foam dewars use fine closed cell foam for insulation, which is chemically inert and mechanically durable enough to be exposed directly to liquid nitrogen, without leaking or degrading.

Also, due to the lower thermal mass, foam vessels cause less liquid nitrogen boiloff when filled, and will accumulate less frost. This results in less liquid nitrogen being used.

All vessels feature a foam lid.
