CoolCube™ Microtube and Microplate Cooler is designed to store samples safely on lab bench without sample degradation due to temperature increase or fluctuation. Constructed of DuraStar （a high strength polymer） and a proprietary gel refrigerant, CoolCube maintains temperature at approximay 0°C for up to four hours. Simply place the CoolCube in a freezer overnight and it's ready for use, keeping samples cool and safe at the bench, without messy ice buckets or wet tubes. One side of CoolCube can be used as a convenient PCR workstation, with wells for 10 standard 1.5/2.0ml microtubes and one 96 well PCR plate or .2ml tubes/strips. The other side can be used to hold 36 standard 1.5/2.0ml microtubes.
