The Quattroflow pump systems, featuring special Masterflex drives, are designed to safely and reliably pump delicate biologic fluids. The Quattroflow pump heads offer a unique four diaphragm (chamber) design, providing the constant low-pulsation, low-shear pumping needed for your biological fluids. In addition, the quaternary diaphragm design enables risk-free dry-running, self-priming, and a high turn-down ratio. Both the single-use and multiple-use models safely and reliably pump plasma products, proteins, monoclonal antibodies, vaccines, and more.
Single-use pump heads have a disposable wetted chamber constructed of solid polypropylene (PP) that can be replaced as a complete unit. This saves you time and money by eliminating the cleaning validation, sterilization process normally associated with permanent multiple-use systems. You can quickly turn around equipment from one batch to the next, maximizing production operations. Plus, fluid path integrity and sterility is ensured with no chance of cross-batch or cross-product contamination. Come presterilized and double bagged. It is recommended you replace the pump head every 1000 hours of operation.
Multiple-use pump heads ensure total product containment without abrasion and minimal particle creation. Stainless steel construction handles higher pressure applications including cross-flow filtration and chromatography columns.
The special Masterflex drives, enclosed in ABS plastic or stainless steel, were developed to best take advantage of the operating parameters of the Quattroflow pumps. They feature an intuitive interface, remote control functionality, and a brushless, maintenance-free motor with ±0.1% speed control accuracy. The graphical LCD shows six different parameters: motor rpm, flow rate, dispense volume, cumulative volume, dispense interval time, and copy number. Dispense by volume or time with a user-defined time interval between cycles.
The plastic-enclosed drives have an IP33 rating for benchtop lab applications and have been combined with the lower flow QF150 series pump head.
Stainless steel drives have IP66 and NEMA 4X ratings and are designed for both the QF150 and QF1200 series. Sealed stainless steel housing and sealed keypad are protected from dust, water, and chemicals in the washdown environment—simply hose down to clean.
