Description of PES Syringe Filter:

Polyethersulfone(PES) syringe filter is provided by HAWACH, with natural hydrophilicity, narrow pore distribution, precise pore size:0.1μm, 0.22μm, 0.45μm, etc. The filter also with no pollution to samples, low resistance, fast filtration, and good chemical resistance, has a very good effect on the filtration and clarification of samples.

Advantages of Hawach PES Syringe Filter:

  • HAWACH supplies Standard Disposable, Advanced, and Sterile PES syringe filters.
  • The shell material of the syringe filter is made of high-quality medical-grade polypropylene material
  • And the product structure design is precise, which ensures smooth filtration, rationalization of the internal space, and a very low residual rate, thus reducing the waste of samples.
  • In HPLC analysis, the particle size of chromatographic column packing is small and easily blocked by impurity particles, so samples and solvents need to be pre-filtered to remove particulate contaminants and protect the instrument.

Features of  Hawach PES Syringe Filter:

  • The sterile PES syringe filter is widely used in the laboratory, it does not need to change the membrane and clean the filter, which saves the complicated and time-consuming preparation work.
  • Mainly used for sample pre-filtration, clarification, removal of particles, and sterile filtration of liquids and gases.
  • It is the method of choice for the filtration of small samples by HPLC and GC.
  • The shell of the syringe filter is made of medical-grade PP plastic, and the upper and lower parts are welded together by ultrasonic waves, which are resistant to high pressure and have no product leakage problem.
  • Stable membrane quality and zero batch-to-batch variability ensure consistent analytical results.
  • The Polyethersulfone membrane (PES) syringe filter has a high filtration rate and low protein adsorption.
  • Standard with a locking Luer interface, the connection is tighter.
  • Faster passing speed compared to PTFE syringe filter and PVDF syringe filter.


  • Suitable for rapid sterile filtration of media, buffers, and other aqueous solutions.
  • Sterilization filtration of protein solutions.
  • Filtration of tissue culture additives.
  • It can be used in HPLC analysis and IC analysis.
  • It is suitable for different water systems and organic system solution filtration.
