Product description

In a typical chromatography process, there are five membrane valves that connect the chromatography column to the process tubes. The operation of these valves allows the process to flow back and forth through the chromatography column, as well as completely bypassing the column. With the Pure-Flo Integral Chromatography Valve Assembly, this is achieved by installing the necessary valves while maintaining flexibility, minimizing dead legs in the process tubes, and reducing the overall footprint of the assembly. The integral chromatography valve serves the process requirements of three (3) P&IDs. It contains four or five valves in a fabricated assembly, significantly reducing contact areas and hold up volume.
