Bio-Rad Cooling Module Catalog Numbers Bio-Rad 170-3654, Bio-Rad 170-3655, or Bio-Rad 170-3688 Bio-Rad Chef-DR Cooling Module used nice
The Cooling Module has been specifically designed as a stand alone, portable refrigerat- ed apparatus for use with the CHEF-DR® II, CHEF-DR III, GenePath®, and CHEF Mapper® pulsed-field instruments. Electrophoresis buffer is circulated from the electrophoresis chamber by the variable speed pump, cooled directly by the liquid refrigerant in a heat exchanger within the Cooling Module, and returned to the electrophoresis chamber. The heat exchanger is electrically isolated from the chassis, compressor, and plumbing to eliminate electrical shock hazard.
The Cooling Module maintains a constant buffer temperature typically within 1 °C of the set temperature (after stabilization) in an operating range of 5––25 °C for a total buffer capacity of 2.2 liters at a flow rate of 1.0 liter/minute. Maximum buffer cooling capacity is 75 Watts (255 BTU) of input power at a set temperature of 14 °C
