MediaScout^® ValiChrom Validation and Scale Down Modelling Columns

ValiChrom columns combine an unique set of features to ensure the highest possible validity of validation data in a scale down model column:

• Performance closely matches that of the full-scale process column
• Replicate columns deliver similar performance
• Columns are packed with customer's own process resin
• Fixed bed height identical to the process column
• Packed with optimised / controlled compression
• Individual column performance certification
• Alternative diameter precision bore glass tubing
• Simple, low cost purpose designed column design
• Available to reliable lead time

ValiChrom columns are a cost effective solution to assuring high quality data from professionally packed columns. They are available in convenient geometries and are packed to correct compression for any resin type from any manufacturer.

ValiChrom Columns are packed with the resin specified by the customer, with specific resin lot number if supplied and in replicate units conforming to packing specifications. Each column is supplied with its own Certificate of Performance.


Any column length is available to match that of the individual process column.

Alternative diameters provide 0.2, 0.5, 1.0, 2.0, 4.0 and 10ml/cmL             Lengths from 10 - 60 cm

Certification for asymmetry factor, plate number and pressure flow performance.


Typical uses for ValiChrom columns:

• Virus Clearance Studies
• Functional Scale Down Modelling
• Resin Lifetime Evaluation Studies
• Resin Lot-to-lot validation
• CIP method validation
