You Searched For: Pumps

Peristaltic pumps rely on compressing and releasing a length of flexible tubing to mimic natural peristalsis seen in many biological systems, using positive displacement to move fluids in a pulsing manner. Procedures will remain contamination-free using these systems, since the only part of the pump touched by the solution is the interior of the tubing. Additionally, the pumps are able to handle heavier and more aggressive fluids. The flexible tubing requires few periodic replacement and maintenance needs.
