Clarification Depth Filters & Pretreatment Solutions

Our clarification portfolio provides flexibility to the biopharma manufacturer for efficient cell, cellular debris, and other insoluble contaminant removal and impurity clearance from different process streams from process development through large-scale manufacturing. Millistak+®, Millistak+® HC Pro and Clarisolve® Depth filters are available in Pod devices.

Section Overview



Millistak+® HC Pro Filters

Millistak+® HC Pro Filters

MILLISTAK+® HC PRO FILTERS

These are high capacity fully synthetic depth filters for primary and secondary clarification and downstream polishing applications and are available in Pod format for easy set up and use.

These filters are cleaner and have improved lot to lot consistency as compared to diatomaceous earth (DE) and cellulose (CE) based filter media.

Millistak+® Depth Filters

Millistak+® Depth Filters

Millistak+® Depth Filters

These filters are offered in both Pod and lenticular formats. 

  • Millistak+® HC filters combine multiple layers of charged depth media for enhanced particulate retention and filter capacity for clarification and polishing applications.
  • Millistak+® CR40 filters contain activated carbon in a cellulose matrix and enhance clearance of HCP and impurities in polishing applications.
  • Millistak+® DE filters are single layer clarification filters containing diatomaceous earth and a charged resin binder for primary or secondary clarification applications.
  • Millistak+® CE filters are single layer clarification filters containing cellulose for coarse, primary clarification applications.
Clarisolve® depth filters and polymers

Clarisolve® Depth Filters and Flocculation Polymers

Clarisolve® depth filters offer a gradient density structure designed for efficient primary clarification of pretreated  cell culture harvests.

  • pDADMAC (poly(diallyldimethyl-ammonium chloride) is a cationic polymer for flocculation of cellular debris.

Support for Qualification, Risk Assessment, and Process Optimization

Complementing our product portfolio, the Emprove® Program provides three types of dossiers to support different stages of development and manufacturing operations such as qualification, risk assessment, and process optimization. The dossiers consolidate comprehensive product-specific testing data, quality statements, and regulatory information in a readily available format to simplify your compliance needs.
