Filter Material Specs

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

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
• After pre-wetting with alcohol, may be used for fine particle removal of aqueous and mild organic solutions in Ion Chromatography

Syringe Filter Capabilities

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.
