The CoolCube™ is designed to store samples safely on the lab bench without sample degradation due to temperature increase or fluctuation. Simply place the CoolCube in the freezer overnight and it's ready for use, keeping samples cold, but not frozen. One side of the CoolCube will hold 36x1.5/2.0ml tubes. Flip it over, and you have a PCR workstation. This side holds one 96 well PCR plate (or 96x0.2ml tubes) and ten 1.5/2.0ml tubes. CoolCube maintains temperature at approximately 0° C for up to four hours on the bench.
