Mini Pro 300V Power Supply | Electrophoresis Power Supply

The Mini Pro 300V power supply is an outstanding value for the lab an ideal choice for any researcher. Combining small size and versatility, the Mini Pro 300V power supply is capable of providing constant voltage or constant current in 1V or 1mA steps. The unit is perfectly suited to run both vertical polyacrylamide or horizontal agarose gel electrophoresis experiments.

Continuous or timed operation are easily performed using the simple and user-friendly interface. The Mini Pro 300V features 2 electrode pairs, allowing for 2 gels to be run simultaneously, saving both time and valuable bench space. With a universal voltage rating, the Mini Pro 300V is also designed and constructed to the most rigorous safety standards. Packages including single or dual horizontal electrophoresis systems and mini vertical electrophoresis systems are excellent choices for educational or personal use.
