ABSTRACT:
A buffer solution being used in an electrophoresis cell as both an electrode buffer and a cooling medium is circulated through a refrigeration system external to the cell without risk of arcing or other danger despite the electrified state of the buffer solution. The refrigeration system contains a circulating coolant, a shell-and-tube heat exchanger, various components for the coolant such as a compressor, condenser and capillary, and preferably also a by-pass which, on command from a temperature control unit, passes warm coolant from the compressor discharge directly to the heat exchanger. Couplings of dielectric material insulate the heat exchanger from the remaining components of the refrigeration system.
