CryoGuard™, 41,600 Vials

Product Number: CGSP-2

The CryoGuard™ Class from CryoSafe™ has been specifically engineered to provide cryogenic vapor temperatures throughout the tank well below the critical -135°C range. With only a few inches of liquid, vapor temperatures as low as -180°C can be maintained at the highest shelf. Maintaining temperatures below the glass transition temperature of -135°C helps insure long-term cell viability.

CryoGuard’s™ restricted-opening neck design with double-hinged lid brings LN₂ consumption to one of the lowest rates in the industry. In vapor phase operation, LN₂ is stored out of the inventory storage area helping eliminate cross contamination issues. THE CGSP-2 has a unique inventory holding container is engineered to maximize the use of 81/100 cell box racks to meet capacity needs up to 41,600 each 2 ml vials. This feature improves cryo vial inventory, placement, tracking, and retrieval.

Every CryoGuard™ comes standard with: 6ft. stainless-steel armor-plated transfer hose, 3/5 warranty, PowerGuard™ battery backup, casters, folding step, inventory carousel, keyed lid lock, LN2 measuring rod, flat stainless-steel work surface and the Sentry Plus controller.  Package systems are available with CryoGloves, and either polycarbonate or fiberboard inventory boxes with or without grids and dividers.
