    product description


    In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument.

    Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment.

    Syringe filters can be used in HPLC analysis and IC analysis to filter sample solutions, which is an important step in the sample pretreatment process.

    Membrane Characteristics

    Membrane Material



    hydrophilic or hydrophobic, resistant to strong acid, strong alkali and high temperature, suitable for the filtration of strong corrosive solution, organic solution and gas.


    hydrophilic or hydrophobic, low protein binding, suitable for general biological filtration, not suitable for filtration of highly corrosive liquids.


    hydrophilic, high protein binding, suitable for protein-free aqueous and organic solutions, resistant to alcohol and DMSO.


    hydrophilic, low protein binding, high flow rate, high porosity, not resistant to organic


    hydrophilic, low protein binding, suitable for the filtration of proteins and aqueous solutions in biological samples, such as serum culture medium filtration.


    Excellent contrast for easier particle detection, high degree of internal surface area, Higher dirt loading capacity, high flow rates, Thermally stable

    Syringe Filter Membrane Pore Size:

    0.22um: Sterilization grade filter membrane, sometimes written as 0.2um, can remove very fine particles in samples and mobile phases; it can meet the requirements of 99.99% sterilization specified by GMP or Pharmacopoeia;

    0.45μm: usually used for pretreatment to reduce the microbial load and filter out most bacteria and microorganisms; conventional sample and mobile phase filtration can meet general chromatographic requirements;

    1-5μm: To filter larger particles of impurities, or for the pretreatment of difficult-to-handle turbid solutions, it can be filtered with a 1-5μm membrane first, and then filtered with the corresponding membrane.
