Liquid Nitrogen Refrigerator 45 Liter Capacity
This high quality cryogenic refrigerator, liquid nitrogen cooled, has a 45 liter capacity. It is known for its extremely low daily evaporation loss. Note that it does not come with canisters, which have to be purchased separately.
Note: The term "refrigerator" is generally applied to those devices for which the principal purpose is to provide cooling of samples, that is, long term storage in a cryogenic environment. Since samples are constantly being added to or withdrawn from the chamber, a refrigerator generally has a wide mouth [e.g. larger than 5" (12.7 cm)].
The term "dewar" is generally applied to those devices for which the principal purpose is to serve as a reservoir or holding tank for liquid nitrogen, which is destined to be poured into some other volume or device that is to be cooled. Because it is not meant to store samples and is meant to be used as a pouring device, the units are characterized by a narrow mouth, typically about 2" (5
