This cooler safely holds thirty-two 0.5, 1.5 or 2.0ml microcentrifuge tubes or cryo vials at a temperature below -15ºC for approximately 1½ 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 polycarbonate lid extends temperature holding time and is secured closed with a 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 24 hours prior to use.
