Filtration Media / Application Guide (hydrophobic or hydrophilic)
Glass microfiber filter media - prefilter versions available in all variations

Mixed Cellulose Esters (MCE) - Hydrophilic

  • This membrane is recommended for all filtrations in aqueous or polar media, bacteria filtration
  • Ideal when maximum protein recovery in filtrate is crucial
  • Used for filtration and inspection of gas, oil and alcohol particulate and bacteria
  • Combined with glass microfiber prefilter, ideal for tissue culture media and sensitive biological samples
  • Sample filtration - prefilter increases yield

Cellulose acetate (CA) - Hydrophilic

  • Very low binding capacity for proteins.
  • Material is nitrate-free making it suitable for groundwater & EPA ASTM’s.
  • For filtration under sterile conditions
  • Filtration and clarification of biological fluids, sterilization of media additives and serum
  • Sample preparation of aqueous solutions
  • For applications requiring maximum sample recovery
  • Sample preparation of protein-based HPLC solutions
  • Designed to sterilize and remove particulates from even the most viscous proteinaceous samples
  • Filtration of tissues culture media with glass fiber prefilter

Polyamide/Nylon (PA) - Hydrophilic

  • Hydrophilic material; it is recommended for filtration of aqueous or organic/aqueous medium polar liquids.
  • Commonly used for general laboratory filtration and filtration of HPLC and GC samples prior to injection
  • Filtration of aqueous and organic-aqueous polar medium liquids
  • Dissolution sample analysis
  • Suitable for use with high pH samples
  • Since it binds proteins it is NOT suitable for protein recovery applications
  • With microfiber prefilter higher absorption capacity for contamination

Polyethersulfone (PES) - Hydrophilic

  • High filtration flow rates
  • An inherently low affinity for proteins.
  • Low extractables
  • Introduction of additives into tissue culture vessel.
  • Certified for Ion Chromatography
  • Final filtration of bacteriophage and infusion solutions
  • Tissue culture, proteins, buffer and nucleic acids filtration
  • Ideal for applications requiring maximum sample recovery
  • Filter hybridization solutions and probe to reduce backgrounds
  • Food, beverages and ultra pure water final filtration
  • Sterile product individually blister packed

Polyvinylidene difluoride (PVDF) - Hydrophobic

  • This membrane features a stability and hydrophobic interactions similar to PTFE.
  • Recommended especially for filtration of water-soluble oligomers and polymers, e.g. protein solutions.
  • Can also be used for the filtration of hydrophobic substances in different organic solvents.

Polytetrafluoroethylene (PTFE) - Hydrophilic or Hydrophobic

  • PTFE membranes are inherently hydrophobic; they are ideal for the filtration of nonpolar liquids and gases.
  • Very resistant to solvents as well as acids or bases.
  • Can be made more hydrophilic by flushing with alcohol, followed by water
  • Used for filtering and de-gassing chromatography solvents
  • Permits optimal utilization of small sample volumes
  • Excellent chemical compatibility for filtering harsh chemicals that destroy other membrane materials
  • Moisture barrier for venting applications and vacuum pump line protection
  • Ideal for aerosol sampling
  • Filter viscous organic based HPLC samples
  • Glass microfiber prefilter raises absorption capacity and loading
  • After pre-wetting with alcohol, may be used for fine particle removal of aqueous and mild organic solutions in Ion Chromatography

Glass Fiber Prefilters

  • For viscose solutions or for turbid liquids
  • Ideal for use as a prefilter in series with other syringe filters
  • Glass microfiber filter media enclosed in this series is binderless 1.0µm retention
  • Reduces clogging of the membrane, so ideal as a prefilter to increase throughput and flow rate
  • Ideal for dissolution testing and general filtration
  • Applicable to all membrane types, allowing higher flow rates

Beyond the extensive product selection found within our standard syringe filter list, we offer OEM capabilities for engineering, molding and insertion of many additional membrane and membrane/pre-filter options.   We can work with most of our own membrane and specialty materials as well as convert your supplied product.  Please contact us for full engineering capabilities as well as process flow and project management services in this field.

  • Filter insertion in clean room by manual as well as fully automated means.
  • Molding in place, over molding and support structure molding of fragile media.
  • Ultrasonic welding of barrel structure for increased leak / burst resistance.
  • Multi-process mold extensions for inclusion of single or multi-level prefiltration media.
  • Digital variable print capabilities along arc on barrel face for identification purposes.
  • Blister packing for EO and gamma sterilization.
  • Pure virgin PP, verified by HPLC against U/L extractables.
