A clear polycarbonate lid shows positions of tubes and is keyed to correspond with positions printed on the cooler. Molded side handles allow secure grip for transfer. Coolers are stackable and have rubber feet to prevent sliding on the lab bench. Ideal for protecting valuable samples stored in a freezer with defrost cycle. Use included insert to hold 0.5ml microcentrifuge tubes. Store at -20ºC for 24 hours prior to use.
