Depth Filters

 

Depth filters are ideally suited for demanding prefiltration, cell harvesting, and post virus inactivation clarification processes in biopharmaceutical and biotech applications. Biotech depth filters remove cell debris and contaminants, ensuring better protection to downstream purification processes such as chromatography and sterile filtration.

Media grades comparison

 

 

Seitz Bio-series
  • Single layer media made of highly purified, natural/modified cellulose fibers
  • No inorganic additives such as diatomaceous earth (DE), perlite, or glass fiber
  • Low release of extractables
  • Low protein adsorption
Seitz P-Series
  • Single layer media specially developed for biotech/pharmaceutical industry, high purity medium
  • Contains inorganic additives such as diatomaceous earth (DE), perlite, or glass fiber
  • No recycled materials
  • Low virus retention
Seitz AKS-Series
  • Embedded with activated carbon
  • Suitable for decolorization and removal of other impurities
Seitz HP-Series
  • Double layer of P-Series depth filter sheets
  • Suitable for low viability/high solid containing applications

Applications

 

 

Considerations when Selecting Media
Particle Distribution Size
  • Cell size
  • Total and viable cell density
  • Cell viability
  • Lysis process
Cell Culture
  • Adherent or suspension
  • Cell line
  • Bioreactor or shake flask

 

 

Below are depth filter recommendations for common applications. Media grade can vary based on process conditions so multiple options are provided where appropriate.  Please consult a Pall expert before confirming your selection.
