CryoGuard™, 19,500 Vials

Product Number: CGSP-1

The CryoGuard™ Class from CryoSafe™ has been specifically engineered to provide cryogenic vapor temperatures throughout the tank well below the critical -135°C range. In fact, with only a few inches of liquid, vapor temperatures approaching the actual -196°C temperature of liquid nitrogen can be maintained at the highest shelf. Maintaining temperatures below the glass transition temperature of -135°C helps insure long-term cell viability.

The unique restricted-opening neck design with double-hinged lid brings liquid consumption to one of the lowest rates in the industry. In vapor phase operation the liquid is also stored out of the inventory storage area helping to eliminate cross contamination issues. The unique inventory holding container is also engineered to maximize the use of 81/100 cell box/racks. This feature greatly 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 iSentry Plus controller.  Package systems are available with CryoGloves, and either polycarbonate or fiberboard inventory boxes with or without grids and dividers.
