Pump operates at laboratory and production scales
Watson-Marlow Bredel (Wilmington, MA) has introduced its “520Di” pump for filtration, fermentation, and dispensing applications. The machine’s ramp-and-drip feature enables a soft start and graduated dosing to reduce splashing and foaming while the product is being pumped. Users can perform periodic dose recalibration without disturbing the flow of the batch.
The 520Di device is suitable for laboratory applications such as preparing benchtop media and reagents. In addition, the unit can accurately perform production-scale filling of pharmaceuticals and biopharmaceuticals. The 520Di machine can perform batch dispensing and automatic or single-shot dispensing of sensitive fluids in sanitary environments.
Watson-Marlow Bredel’s 520Di pump accepts eight different tubing materials and tube sizes as large as 9.6 mm. The device operates at flow rates ranging from 4 µL/min to 3.5 L/min at pressures as high as 100 psi.
