Abstract
A method of (and apparatus for) electrophoresis in which the gel temperature is controlled automatically. A sensor may measure a gel temperature and a processor may control a power supply for the electrophoresis process in response to that measurement. Measurements may be made at predetermined times (e.g., periodically) and the processor may determine control settings for the power supply based on a preferred temperature for the electrophoresis process. The preferred temperature for the electrophoresis process may be a predetermined temperature which is chosen so that the electrophoresis process operates at or near the highest speed which is unlikely to break the glass plates.
