Electron Microscopy Sciences Foam Cryo Dewars - Mini Vessel

Electron Microscopy Sciences The foam dewars are safe, durable containers for handling liquid nitrogen and cryogenic materials. 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. They have superior insulating properties compared to stainless or glass, at a fraction of the cost. Also, due to the lower thermal mass, foam vessels cause less liquid nitrogen boil off when filled, and will accumulate less frost. This results in less liquid nitrogen being used.
