Bio-Rad Cooling Module Electrophoresis buffer is circulated from the electrophoresis chamber by the variable speed bump, 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 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 of input power at a set temperature of 14 C.
