Peristaltic Pump

Peristaltic pumps are one of the most common types of pump used in laboratories. These are a type of positive displacement pump used to move fluids forward and backward through a flexible tube.

This tube is squeezed by rotating rollers against a rigid casing. As the rollers move along the tube, they create a vacuum that draws fluid into the tube and pushes it out at the other end.

The key features of a peristaltic pump includes precise flow control and the ability to handle a wide range of viscosities and particulates. Because fluids are only in contact with the tubing, peristaltic pumps become ideal tools for sanitary or corrosive applications especially for medical, laboratory, and industrial settings.

More about Peristaltic Pump

Also known as a roller pump, a peristaltic pump works on the principle of peristalsis. Peristalsis is the rhythmic contraction and relaxation of muscles that move fluids through tubes.

A peristaltic pump can pump a wide variety of fluids, such as viscous liquids or gases. It is useful for laboratory applications that require low-pressure transfers of fluids, such as biochemistry analyzers, colter counters, electrolyte analyzers, etc. 

Some advantages of peristaltic pumps are that they are easy to use, self-priming, reversible, and prevent cross-contamination between fluids and tubing. Some disadvantages are that they have limited flow rates, pressure ranges, and tube life.
