Sanitary dispensing pump for biotech, pharmaceutical drug manufacturing

June 16, 2008

Watson-Marlow Bredel launches its 520Di dispensing pump for accurate metering, dosing and transferring of sensitive fluids in sanitary environments. Ideal for filtration, fermentation and dispensing applications, the 520Di accepts eight different tubing materials and sizes up to 9.6mm for flow rates ranging from 4 microliters/min up to 3.5 liters/min and pressures up to 100 psi. The 520Di combines the rugged ability to perform in process applications with dispensing and dosing programming to handle the most delicate laboratory environments and the accuracy demanded in filling lines in biotech and pharmaceutical production. The 520Di is also suited for benchtop media or reagent preparation in laboratory suites – filling or inoculating bottles, vials, petri dishes and media bags Featuring spring loaded stainless-steel rollers and a larger swept volume pump head, the 520Di combines the gentle handling of fluids with a greatly increased capacity. The gentle nature of the peristaltic pumping action is important for this type of application because of the fragility of protein string, enzyme-based vaccines and other biochemicals, which can be easily damaged.
