MP-300V Power Supply | Electrophoresis Power Supply

The Major Science MP-300V power supplies are designed to meet most electrophoresis needs, running horizontal & vertical electrophoresis, and two-dimensional electrophoresis, or SDS-PAGE applications.

The MP-300V is recognized as the most powerful unit in its market class, capable of running 4 systems simultaneously. Its design provides a compact and modern stackable case. Microprocessor control offers an easy user interface. The user has control of constant voltage output as well as constant current output. Pause/resume functions and a timer with alarm allow run capability during timed or continuous operation. The safety devices include no load detection, leakage detection, sudden load change detection, over temperature protection, and over load detection.
