Filtration Pumping

BPI_A_080602AR10_O_I_76570a.jpg


Product: 620RE filtration pump

Applications: Dead-end filtration and tangential flow filtration (TFF)

Features: Gentler on the product in terms of shear stress when producing higher yields; provides unrivaled performance with a control ratio of 2650:1; requires minimal maintenance with no valves or seals to clog, resulting in reduced downtime; offers exclusive innovative PIN-secure protection feature that provides two levels of PIN protection; speed range can be capped to prevent accidental damage to delicate filters; keypad functionality can be disabled to avoid inadvertent changes to pump settings in sensitive fermenation processes; pumps contain fluid in the tubing at all times, never allowing the fluid to come into contact with the pump mechanism and ensuring gentle, low shear handling
