Mini Pro 300V Power Supply, MINI-300

產品型號: 5-02-Mini-300


Featuring in small size and versatility, the newly designed Mini Pro 300V / 500V electrophoresis system is an ideal choice for researchers. Capable of providing constant voltage or current in 1V or 1mA increment, the unit is perfectly suitable to run both vertical polyacrylamide or horizontal agarose gel electrophoresis experiments. Continuous or timed operation can be easily set up with the simple and user-friendly interface. Moreover, the upgraded 2-step programmable function is more practical for protein electrophoresis. Mini Pro 300V and 500V both are featured with 2 electrode pairs, allowing 2 gels to be run simultaneously, saving both time and valuable bench space. With a universal voltage rating, Mini Pro 300V and 500V are also designed and constructed to the most rigorous safety standards.
