Cryogenic Storage Systems and Supplies

Are you looking for reliable cryogenic storage systems and supplies? We’ve got that and more.​

MIDSCI has a wide selection of cryogenic storage products; including entire systems, refrigerators, and tanks.
The K Series Cryostorage Systems we carry offers reliable liquid nitrogen storage from -100°C to -196°C. These systems have a unique Temperature Gradient Suppression System that greatly improves vapor phase storage temperature and recovery.
Other than entire cryogenic storage systems, we also offer cryogenic refrigerators, such as the LS3000. This rugged product can lower your operating cost per vial!
And for confined workspaces, consider the XTL3 cryogenic storage tank.
