Bio-Rad Model 250/EX Power Supply

This used Bio-Rad Model 250/EX power supply is a compact, general purpose electrophoresis power source designed for routine gel work in teaching and research laboratories. It provides adjustable constant voltage and current output suitable for standard agarose and polyacrylamide gel runs, and it has long been valued for its simple, reliable operation. The unit has been inspected and functions properly, showing cosmetic wear typical of its age and prior use. Operation is straightforward with analog or basic digital controls for setting voltage and current limits, and the unit includes standard safety features such as lead detection to prevent unintended operation. Its modest footprint and dependable output make it a favorite for smaller labs or classroom settings running basic nucleic acid separations. All output jacks and control functions have been checked and operate as expected for a unit of this vintage. This power supply is well suited for educational labs, small research groups, or as a backup unit for facilities that already own higher capacity Bio-Rad power supplies. It delivers dependable, no frills performance for everyday electrophoresis needs at a fraction of the cost of newer models. The unit is sold as pictured with power cord included.
