Cryo-Safe™ Microcentrifuge Tube Cooling Racks

Cryo-Safe™ Microcentrifuge Tube Cooling Racks safely holds multiple 0.5 to 2.0mL microcentrifuge tubes or cryogenic vials at a temperature below -15°C for extended lengths of time. Included inserts adapt wells to hold 0.5mL microcentrifuge tubes. The polycarbonate cooler body of these microcentrifuge tube racks is filled with a non-toxic gel which cannot contact tubes, ensuring that markings and labels on tubes are safe. A polycarbonate lid that 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. Ideal for protecting valuable samples stored in freezer with defrost cycle.
