Bel-Art 0ºC Cryo-Safe Benchtop Cooler, 4x8 Layout, Holds 0.5 and 1.5 mL Tubes or Vials, Red

Benchtop sized cooler holds thirty-two 0.5 or 1.5ml microcentrifuge tubes at a temperature below 0ºC for approximately 3 hours. The polycarbonate cooler body is filled with a non-toxic gel, which cannot contact tubes, ensuring that markings and labels on tubes are safe. The gel-filled white polycarbonate lid extends temperature holding time and is secured closed with the built-in wire carrying handle. Corresponding tube positions are printed on the keyed lid and near each well. Coolers are stackable and have rubber feet to prevent sliding on the lab bench. Use included insert to hold 0.5ml microcentrifuge tubes. Ideal for protecting valuable samples stored in a freezer with defrost cycle. Store at -20ºC for a few hours until the temperature of the cooler falls below 0ºC.
