Thin-layer electrophoresis: heat dissipation by use of refrigerated air

Abstract

The passage of refrigerated air through the electrophoresis chamber for dissipating the heat produced during thin-layer electrophoresis has been studied for thin layers of kieselguhr G with 0·05 M borax as electrolyte. The results obtained indicate that refrigerated air has potential, both in efficiency and simplicity, for heat dissipation at high potential gradients. In addition, the value of thin-layer micro plates in small electrophoresis tanks is discussed in relation to the consequent availability of high voltage gradients from low-voltage power packs.
