Peristaltic Pumps

Peristaltic pumps are precise, reproducible, and versatile pumps used for transferring liquids. They operate by compressing and releasing flexible tubing in a circular motion to push liquids through the tubing without exposing the fluid to mechanical parts. Common varieties include compact variable-speed peristaltic pumps, digital dispensing systems, and precision process drives from leading brands. They are constructed of durable materials like stainless steel and engineered plastics. Peristaltic pumps are ubiquitous in laboratories worldwide for accurate, contamination-free pumping and dispensing of reagents, cell culture media, buffers, and other aqueous solutions.
