DESCRIPTION 

Combining small size and versatility, the newly redesigned Roth power supply MINI is an ideal choice 
for any researcher. Capable of providing constant current or constant voltage in 1 mA or 1 V steps, 
the microprocessor controlled unit is perfectly suited to run both vertical polyacrylamide and horizontal 
agarose electrophoresis experiments. Continuous or timed operations are easily performed using the 
simple and user-friendly interface. The Roth power supply MINI 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 Roth MINI is also designed and constructed to the most rigorous safety standards. This 
makes it an excellent choice for education or personal use.
