Description of hydrophobic PTFE Syringe Filter:

Hawach PTFE syringe filter is hydrophobic, which has strong chemical compatibility and can filter almost all organic solvents and strong corrosive chemicals. Pore sizes have : 0.1μm, 0.22μm, 0.45μm,1.0um, 3.0μm, 5.0μm, 10.0μm.

HAWACH hydrophobic PTFE syringe filters are divided into three series: Standard Disposable series, Advanced series, and Advanced Sterile series.

non-sterile syringe filter sterile syringe filter 0.45 disposable PTFE syringe filter

Features of Hawach hydrophobic PTFE syringe filter:

  • All sizes, like 0.45 um PTFE syringe filter has excellent chemical resistance
  • High-temperature resistance, strong acid and alkali resistance, and strong hydrophobicity
  • Like hydrophilic PTFE syringe filter, all of the products with standard Luer interface design
  • Gamma-sterilized Teflon syringe filters are individually packaged and do not contain any heat source, DNA
  • Hydrophobic membrane, suitable for filtration of organic solvent medium samples (including strong acid, strong base) and organic solvent.
  • The PTFE membrane has strong chemical compatibility and can filter almost all organic solvents and strong corrosive chemicals.


  • Filtration of strong chemical corrosive organic solvents;
  • Filtration of strong acid solvents;
  • Gas filtration;
  • Steam filtration;
  • Filtration of air, gases, and hydrophobic chemicals;
  • It can filter almost all organic solutions in chemical, pharmaceutical, environmental protection, electronics, food, energy, and other fields.
  • Extensive chemical compatibility, resistant to strong solvents such as DMSO, THF, DMF, dichloromethane, chloroform, etc.
  • All sizes, like 0.45 um PTFE syringe filter, are used for the filtration of most organic solutions, especially the filtration of strong solvents that cannot be tolerated by other membranes.

About PTFE syringe filter sizes:

  • PTFE syringe filter with 0.45μm pore size

Sed for conventional sample mobile phase filtration, which can meet general chromatographic requirements. Such as a chromatography system for 3μm or larger particle size packing.

  • PTFE syringe filter with 0.22μm pore size

Can remove extremely fine particles in the sample and mobile phase. Such as chromatography systems with fillers smaller than 3μm.

  • PTFE syringe filter with 1-5μm pore size

Commonly used for difficult-to-handle turbid solutions, it can be pre-filtered with a 1-5μm filter, and then filtered with a corresponding filter.
