Foam Cryo Dewars

Foam dewars provide a neat and handy alternative to heavier vessels or the commonly utilized styrofoam shipping containers.
The special foam material is chemically inert and mechanically durable enough to be exposed directly to liquid nitrogen, without leaking or degrading.

Patented design makes the foam vessel easier to handle and safer to use than a traditional low profile glass dewar. Because of its lower thermal mass, a foam vessel will cause less liquid nitrogen boiling when it is filled.
The foam surface will also accumulate less frost. As a result, less liquid nitrogen is consumed.

Available as 500ml, 800ml and 1400ml Cryo Cups featuring convenient protruding handle, a Tall (1800ml) vessel, and a Mini (130ml) vessel.
