Overview - VWR International 250V Instruction Manual

Introduction

Overview

The 250V Power Supply is a microprocessor-controlled power supply designed to meet most
electrophoresis needs in a single easy to use unit. The power supplies small foot print and
stacking feature use minimal bench space. The power supply is capable of running constant
voltage/constant current applications and programming mode concurrently. This instrument is
ideal for DNA/RNA electrophoresis, SDS-PAGE, native PAGE, and IEF applications. With
four sets of output jacks that can be used simultaneously, the 250V Power Supply is designed
to run applications at maximal efficiency. The 250V Power Supply offers three modes,
Constant Voltage, Constant Current and Constant Wattage Mode. This manual describes the
setup and operation of 250V Power Supply including important information on safety and
maintenance of the unit.
