Power Supply

A power supply for electrophoresis is an electrical equipment whose function is to manage the current in a constant and direct way to the electrophoresis system, as well as to indicate and control both the supply voltage and the current consumption.

This device acts as a transformer, rectifier and as a regulator at its output, to avoid voltage peaks that damage the electrophoresis system. Electrophoresis is a technique based on the migration of molecules through a gel or matrix of porous nature, to which an electric field is applied, to separate these molecules according to their size or molecular weight, thanks to the action of a power source for electrophoresis chambers, since this component is responsible for providing the electric field necessary to move or mobilize the molecules.

Types of Lab Power Supply a Lab May Need

High-voltage Power Supply

  • Molded housing, touch keys, intelligent microprocessor control;
  • With automatic memory function;
  • With standard timing operation function;
  • Automatic detection of no load, overload and overload.

Kalstein electrophoresis power supplies are specially designed to work with horizontal and vertical electrophoresis chambers. They have microprocessors that control their operation. The power supplies allow working at constant voltage and also have a timer to work at specific time periods during which the process can be stopped and resumed later.

Universal Power Supply

A power supply for electrophoresis systems acts by converting the alternating current coming from the power supply into direct current, and distributes it to the devices that request it. That is why it acts as a transformer, rectifier and as a regulator in its output, to avoid voltage peaks that damage the system.

The power of the electrophoresis power supply is designed for use in the separation of DNA, RNA and proteins. Therefore, failures in the power supply of the electrophoresis system can in turn generate failures in the execution of the technique, which is why it is necessary to make sure that the power supply works correctly and that its capacity is sufficient to cover the energy needs of all the internal components of the system.
