Pre-packed columns for process validation

OPUS ValiChrom

OPUS® ValiChrom® Columns are high performance glass pre-packed columns designed to be exact scale-down models of corresponding full-scale chromatography columns.  Each column is individually flow-packed according to validated packing protocols with the precision of 1 mm bed height.

OPUS® ValiChrom Pre-packed Columns

With over 10,000 columns packed since 2007, OPUS® ValiChrom® Columns are uniquely suited for process validation. They are designed to match chromatographic efficiency and bed height of production scale columns with a precision of 1mm, making them ideal for parameter evaluation, process validation, and viral clearance studies.

  • Pre-packed with user-specified chromatography resin - over 300 resins
  • Can be packed to any desired bed height between 5 and 60 cm
  • Flow-packed with correct resin compression factor to simulate performance of process columns
  • Convenient diameter tubing simplifies calculations
  • Fixed bed height standardizes adaptor constructions
  • Jacketed biocompatible precision bore borosilicate glass column allows visualization of resin across the fullbed height
  • Certificate of Analysis (CoA) includes efficiency (Plate/m), asymmetry, and pressure flow rate.

about Repligen Manufacturing

process validation and virus clearance Applications

Process validation

  • Functional scale down modelling (scale down validation)
  • Resin lot-to-lot validation
  • CIP method validation
  • Process robustness studies

OPUS® ValiChrom® Columns demonstrate reproducible packed bed performance for robust validation, as shown in the superimposition of HETP curves from 16 different units.


Because OPUS® ValiChrom® Columns match the bed height of the production scale column with a precision of 1mm, they are ideal for scale-down process validation.

Virus clearance studies

Clearance of virus during chromatographic steps is necessary in case of contamination of the used cell bank. OPUS® ValiChrom® Columns are ideal for testing multiple and identical packed columns to prove log-reduction.
