CoolBox ice-free bench top systems provide sample cooling or freezing without ice, electricity or batteries.  The reusable internal cooling or freezing cartridges provide hours of 0.5 to 4.0℃ cooling or -20 to 0℃ freezing.  CoolBox systems may also be used with dry ice to create a compact portable, snap-freezing workstation for bacteria, virus and proteins.  CoolBox systems accommodate a variety of thermo-conductive CoolRack® and CoolSink® sample modules for microfuge tubes, cryogenic vials, PCR tubes and plates, assay plates and more.
