Easy-to-use unit provides “controlled rate” freezing samples at approximately -1°C per minute, which is required to prevent lethal intracellular freezing and successful cryopreservation.

• Clear polycarbonate construction
• HDPE screw closure
• Universal symbols for clear instructions
• Contains removable polyethylene vial holder

Prior to inserting vials, the unit should be filled with 250 mL of 100% isopropyl alcohol

The body of the container is clear polycarbonate, and the screw closure is high-density polyethylene. Placed inside the container is an 18-well, removable polyethylene vial holder that separates the vials from the isopropyl alcohol. A plastic foam insert surrounds the vial holder. Alcohol-filled containers can be stored at room temperature. Universal symbols printed on the container show instructions for use.

Designed for use with 1.0 or 1.8 mL tubes and vials.

Once the samples have been inserted the unit should be placed in a –80°C mechanical freezer.
