PTFE Syringe Filters are universal filters that are inert to a wide variety of aggressive solvents and strong acids and bases. These syringe filters can also be exposed to high temperatures and are an excellent choice for HPLC sample preparation. We offer PTFE syringe filters in both their hydrophobic and hydrophilic states. PVDF Syringe Filters.

PTFE syringe filters are indicated for filtration of gaseous or organic solvent based samples. Their natural hydrophobic membrane exhibits broad chemical resistance and unsurpassed temperature stability. Due to their hydrophobic nature, PTFE filters can be utilized as a moisture barrier in venting applications.

How to Choose Right Syringe Filter — Filter Membrane Materials Polytetrafluoroethylene (PTFE) PTFE membranes are chemically resistant to nearly all solvents, acids and bases. The membrane has low extractable and good thermal stability. Membrane: HPLC certified PTFE, with polypropylene support

Red PTFE (Hydrophobic) Syringe Filters, 0.45 µm, 13 mm. PerkinElmer. Hydrophobic PTFE syringe filters have broad chemical compatibility and high pH resistance. These are versatile filters for use with aggressive organic solvent-based solutions and are especially ideal for HPLC sample preparation.

Instrument filters are fabricated with galvanized steel frame & media. Specifications include velocity ranging from 300 to 700 ft. per minute, thickness of 2 in. or 4 in. Materials include bronze, stainless steel, Monel® & aluminum.

Hydrophilic PES membrane consists of pure polyether sulfone polymers without support. It can provide good mechanical strength, thermal stability and broad chemical compatibility. It’s applicable for pure water filtration, particles removal of HPLC aqueous mobile phase, preventing column clogging.

HPLC-certified non-sterile syringe filters are available with nylon, regenerated cellulose or polytetrafluorethylene (PTFE) membranes in polypropylene housing for extra chemical resistance. Sterile tissue culture-tested syringe filters are available in PES, regenerated cellulose, or surfactant-free cellulose acetate membranes in either

Membrane Type (PTFE, GHP, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart opposite). For aqueous samples, it is preferable to use a hydrophilic membrane (GHP, PVDF or Nylon) versus a hydrophobic membrane (PTFE).
