VWR® Masterflex® Peristaltic Pumps by Avantor deliver gentle, accurate, and contamination-free pumping by compressing flexible tubing — the fluid never contacts the pump mechanism, eliminating cross-contamination. Available in a wide range of models from compact benchtop dispensing pumps (Masterflex L/S®) to high-capacity industrial process pumps (Masterflex I/P®). Key features include: variable speed control (analogue or digital), reversible flow direction, wide flow rate range (from 0.001 mL/min to >3400 mL/min depending on model and tubing), programmable dispensing modes, and compatibility with a wide range of tubing materials (silicone, Tygon®, Norprene®, C-Flex®, PTFE) for chemical resistance. Ideal for media transfer, chromatography, bioreactor feeding, chemical dispensing, and sampling workflows. Certified for cGMP environments.
