EPS-650R
Rechargeable Electrophoresis Power Supply
80 to 650 V from an internal lithium-ion pack. A full day of runs, with or without mains power.
The EPS-650R is a high-voltage electrophoresis power supply built around a 12 Ah lithium-ion battery. It holds a set voltage to within one volt, meters current continuously and ends every run on a timer, so hemoglobin, serum protein and agarose separations finish cleanly even when the grid does not cooperate.
