Introducing Proxcys TQ-packing systems

Proxcys b.v. has built and installed a range of powerful, versatile and compact Chromatography Packing systems 

Since HP-RFC columns are champions in throughput per square meter Proxcys could not accept the huge space some of the typical packing skids are demanding for a relatively simple task. The industrial size Packing systems share the same famililt characteristics since they are small and powerful. Controlled by the really intuitive COMPANION(TM) scada HMI Proxcys systems pair user friendlyness with cGMP (21CFR) data management.

Industrial size HP-RFC columns combine small footprint with ease-of-use

Tripod HP-RFC columns: Smallest footprint highest throughput

HP-RFC columns will significantly reduce the footprint required for an industrial column. In the example below the 210-230L Tripod column  with a bed height of only 12cm can be nicely tugged away in a corner without compromising acces processing 6000L/h at 300cm/h.!  A perfect match with the popular disposable bad buffer totes that take up enormous space in the cleanroom. Thanks to Tripod HP-RFC now manouvered without risk of injury.
