The 620RE filtration pump is ideally suited for both dead-end filtration and tangential flow filtration applications. The 620RE is gentler on the product in terms of shear stress when producing higher yields - critical when working with protein solutions valued at several thousand dollars per liter. The 620RE is also ideal for a wide range of pharmaceutical applications such as metering, dosing and transferring pharmaceutical products, live cell cultures, nutrients and bioreactor constituents. This pump provides a control ratio of 2650:1. The unit offers an exclusive, innovative PIN-secure protection feature that provides two levels of PIN protection. For general sanitary applications such as purification, the speed range can be capped to prevent accidental damage to delicate filters. In sensitive fermentation processes, keypad functionality can be disabled to avoid any inadvertent changes to pump settings. The keypad can also be disabled in remote installations to prevent tampering.
