Foam Dewars

The Standard Foam Dewar can hold 800 ml of liquid nitrogen. It has been designed to replace large glass dewars, because the foam has superior durability, safety, insulating properties. 
The standard vessel shape is circular, with a protruding handle. Each dewar comes with a matching foam lid to insulate the contents from ambient air. 
Dimensions of the cylindrical cavity in this vessel are 15 cm in diameter by 7 cm in depth. 

The Small Foam Dewar has the same basic shape and features as the Standard Foam Dewar but a smaller diameter cavity . Dimensions of the cylindrical cavity are 11.5 cm in diameter by 7 cm in depth, easily holding 500 ml of cryogenic liquid.

The Large Foam Dewar is a slightly bigger version of the popular standard vessel. Dimensions of the cylindrical cavity in this vessel are 16 cm in diameter by 9.5 cm in depth, so that it easily holds 1400 ml of liquid nitrogen.
