Isocratic Sanitary Packing & Running system

Objective

A packing system offers controlled packing of the column yet the equipment could also be used to condition the resin and create the performance evaluation data at the packing location. The system could even be interesting to be used for simple processing steps.

 

Supplementary demands

  • Accurate shear-less packing pump
  • Simple system layout
  • Robust intuitive MANUAL process control
  • Continuous UV-, pH-, Conductivity-, Pressure- and Flow- reading
  • RAW data to be protected from manipulation (21.CFR.11)
  • Small footprint
  • Low cost!

 

System Description

Configurations

  • ES-Pack PAT20    0-20 l/min
  • ES-Pack PAT3      0-3 l/min

 

The velocity of the pumps is manually regulated but automatically corrected by feed-back of the accurate MAG flow meter. 3 modes of operation:

  • Manual (dial) flow setting, regulated by flow rate reading and feed back.
  • Manual (dial) flow setting not regulated (in case of air or WFI)
  • Purge setting where manual selector valve will allow a short pulse at high or low flowrate (preset to ~80% and ~40% fixed).
