Peristaltic pumps have become the gold standard for shear-sensitive pumping applications where damage to cells or agitation of a suspension or colloidal mixture may interfere with the science being performed. Shear sensitivity concerns are especially common in live cell circulation within a bioreactor or food and beverage suspensions in manufacturing applications. Inherently, peristaltic pump technology provides gentle pumping action at low speeds, especially when compared to other positive displacement pumps which use tightly machined gears or high-speed impellers to move liquids. However, when it comes to providing the maximum protection to sensitive fluids not all peristaltic pumps are designed equally.
The new Masterflex L/S Cytoflow pump head was specifically developed for pumping live cells and shear-sensitive fluids–validated by independent data*. The pump head is ideal for use in biopharma and microbiology applications and performance in live-cell applications.
The Cytoflow pump head has a large-diameter rotor resulting in high flow rates at low motor speeds. The pump head is available in 2- and 3-roller configurations—two-roller heads offer higher flow rates, three-roller heads deliver less pulsation.
In addition to the high flow rates at low motor speeds, the Cytoflow pump head has a convex roller design, furthering its cell viability advantages. This combination makes the Cytoflow pump head the best choice for pump operators looking to minimize the impact on live cells and to maintain the consistency of shear-sensitive fluids.
The pump head is compatible with all Masterflex L/S drives that accept two or more pump heads. You can also choose a peristaltic pump system package that includes Masterflex L/S Digital Process Pump Systems with a Cytoflow pump head.
