Multipurpose power supply can be used for horizontal agarose gel, vertical polyacrylamide gel running, various blotting experiments, etc. Power supply optimized for electrophoresis system. It consists of four sets of output terminals, so four electrophoresis devices can be used at the same time. Space-efficient use with stackable design Folding legs on the lower part make it convenient to operate and check the status. Constant voltage and constant current, Convenient use as two operation modes provided. PC communication via RS-232 Port. Output range 5~250V, in 1V increments 10mA~3000mA, in 10mA increments (Max. 300W) Type of output Constant voltage mode, constant current mode Output terminals 4 pair recessed banana jack in parallel Timer 1min to 99hr 59min
