The Minis 300V power supplies are microprocessor controlled power supplies with universal rated voltage with up to 300 voltage output. This ultra compact sized unit provides enough power to run horizontal agarose or vertical polyacrylamide electrophoresis systems. The Minis 300V series provides 6 different constant voltage selections in timed or continuous operation. Easy operation, dual output terminals, 6 constant voltages, and compact size are the differentiating features. The Minis 300V series is also designed and constructed to the most rigorous safety standards. The packages with 10 x 10 cm vertical electrophoresis or midi sized horizontal electrophoresis systems are valuable choices for educational and personal use.
