VWR Scientific E-C Apparatus VWR 570 DC Power Supply 500V 1.25A Electrophoresis

VWR Scientific E-C Apparatus VWR 570 DC Power Supply 500V 1.25A Electrophoresis

The VWR 570 is a benchtop DC power supply manufactured by E-C Apparatus Corporation and sold under the VWR Scientific brand. It is designed specifically for electrophoresis applications, providing high-voltage DC output with selectable range and switchable constant-voltage or constant-current operating modes. Two front-panel red LED digital displays show output voltage and current simultaneously in real time.

Applications

The VWR 570 is a high-voltage DC power supply purpose-built for gel electrophoresis — the standard technique used in molecular biology and biochemistry labs to separate DNA, RNA, and proteins by size through an agarose or polyacrylamide gel matrix. Electrophoresis power supplies like this one need to deliver stable, adjustable high-voltage DC output (typically in the 100–500V range) and are commonly used to drive horizontal agarose gel systems, vertical PAGE (polyacrylamide gel electrophoresis) setups, and blotting applications. The selectable constant-voltage and constant-current modes allow researchers to run protocols that specify either a fixed voltage or a fixed current. E-C Apparatus Corporation was a well-known manufacturer of electrophoresis equipment for research and academic labs, and the VWR 570 was a standard bench instrument found in university, industrial, and clinical research environments throughout the 1980s and 1990s. Units of this type remain useful today wherever legacy electrophoresis equipment is maintained or budget-conscious labs need a reliable high-voltage DC bench supply.
