Bel-Art 0ºC Cryo-Safe Mini Cooler, 4x3 layout, Holds 0.5 or 1.5 mL Tubes or Vials, Red

Benchtop sized cooler holds twelve 0.5 or 1.5ml microcentrifuge
tubes or cryo vials at a temperature below 0ºC for approximately 2 1 ⁄ 2 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. A clear polycarbonate lid shows positions of tubes and is
keyed to correspond with positions printed on cooler. Molded side
handles allow secure grip for transfer. 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
