Masterflex Quattroflow Single-Use Pump System, 3 LPM, Stainless Steel, Cole-Parmer (CAT#: STEM-DS-0140-LC)

The Masterflex Quattroflow Multiuse Pump System manufactured by Cole-Parmer has a special Masterflex drive to pump fragile biological liquids safely and reliably. The Quattroflow pump head come with a unique four-diaphragm (chamber) design that ensures constant flow with low-pulsation and low-shear force, which is suitable for biological fluids. In addition, the quaternary diaphragm design achieves risk-free dry operation, self-priming and high turn-down ratio. It is able to pump plasma products, proteins, monoclonal antibodies and vaccines safely and reliably with either single-use or multi-use model.
