What is PES Filter?

Filson PES filter has PES as filtration media, including filter membrane, cartridge filter, capsule filter, syringe filter, bottle top filter and many other types. Having high purity raw materials and strict production process, our PES filter is able to perform extremely high performance.

With hydrophilic characteristic, Filson PES filter has high liquid flux that allows the liquid to pass quickly. Its porous structure provides high filtration efficiency and great contaminant retention capacity. It also has extremely low protein binding capacity and extracts.

Filson PES filter is available in both sterile and non-sterile options. Being compatible with autoclaving, EtO, gamma radiation and other sterilization methods, its cleanliness is very high to avoid contaminated sample solution, widely applied in chromatographic analysis, laboratory sample reduction, biological culture, etc.

PES Capsule Filter

Featuring chemical resistance, high flow rate, and low protein binding properties, Filson PES capsule filter includes PES filter membrane and PP capsule housing. Its filter accuracy ranges from 0.1 micron to 5 microns for a variety of laboratory or industrial filtration requirements.

PES Bottle Top Filter

Though gamma radiation sterilized and individually bagged, Filson PES bottle top filter lasts for at least 5 years. Its diameter membrane up to increase more than 44% filtration area than other membrane, which greatly reduce the possibility of clogging during fast filtration.

Common Apertures of PES Filter (3)

  • 0.22 micron PES filter
    Mainly used for sterile filtering, Filson 0.22 micron PES filter has fine and accurate aperture to capture more than 99.9% microorganisms or particulates. We have high standard environment and strict production process, performing 100% sterilized by autoclaving, EtO, γ-irradiation, etc.
  • 0.45μm PES Filter
    Compared with 0.22 micron, Filson 0.45μm PES filter has larger pore sizes that can be used to clarify liquids and remove particles larger than 0.45 microns. With PES as filtration media, it has extremely low protein or medicine binding capacity, realizing maximum sample recovery.
  • 1.2 micron PES Filter
    As one of the most common PES filters, Filson 1.2 micron PES filter contains a variety of types and sizes available to meet most of filtration requirements. It has excellent chemical resistance and temperature resistance, up to 130℃, able to maintain its own property in special environments.
