Description
E-C Apparatus VWR 3000P High-Voltage DC Electrophoresis Power Supply 3000V
The E-C Apparatus VWR 3000P is a benchtop high-voltage DC power supply designed specifically for gel electrophoresis applications. It delivers up to 3000 volts DC with four independent output ports, allowing simultaneous connection to multiple electrophoresis chambers. The unit features a front-panel LED volt display and a numeric keypad for direct voltage programming.

Applications
High-voltage DC electrophoresis power supplies like the VWR 3000P are standard equipment in molecular biology and biochemistry laboratories. They are used to drive gel electrophoresis systems for separating DNA, RNA, and protein samples by size and charge — including agarose gel, polyacrylamide gel (PAGE), and pulsed-field gel electrophoresis (PFGE) setups that require higher voltages. The 3000V output range makes this unit well suited for techniques such as isoelectric focusing (IEF) and 2D gel electrophoresis, which demand higher field strengths than entry-level supplies provide. The four output ports allow a single instrument to power multiple gel tanks simultaneously, a common configuration in high-throughput genomics and proteomics workflows. E-C Apparatus Corporation was a leading manufacturer of electrophoresis equipment from the 1970s through the 1990s, with their products widely distributed under the VWR Scientific and Thermo Fisher brands.
This E-C Apparatus VWR 3000P High-Voltage DC Electrophoresis Power Supply has been powered on and tested at our facility. The display and keypad both function correctly, and each of the four output ports was tested individually under load and confirmed working — note that a load must be connected for output voltage to appear, which is normal operation for this type of supply. The unit is in good used condition with typical cosmetic wear consistent with lab use. Please view our photo set and contact us if you have any questions.
