Provides critical repeatable –1°C/minute cooling rate required for successful cell cryo preservation and recovery.

• Withstands repeated freezing and thawing
• Stackable
• Containers are labeled with graphic, step-by-step instructions

The nonmechanical device is easy to use, as it only requires 100% isopropyl alcohol and a mechanical freezer.The polycarbonate containers are supplied with blue high-density polyethylene closures. Each container is equipped with a gray high-density polyethylene vial holder and foam insert. The rigid vial holder isolates the vials from alcohol, preventing contamination of samples by wicking.

Mr. Frosty containers accept many 1.0 to 5.0mL cryogenic tubes and vials, allowing for cost efficient cell cryopreservation and recovery
