    product description


    Disposable syringe filter devices are designed to provide fast and efficient filtration of aqueous and organic solutions. In HPLC IC 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.

    25mm diameter syringe filter


    diameter of filter membrane: 25mm, 

    diameter of the filter housing: 30mm, 

    the upper port (connecting to the syringe end)

    the outer diameter: 6.5mm, the inner diameter: 4.4mm, 

    the lower port (connecting to the needle end) 

    the outer diameter: 4mm. The inner diameter: 2.2mm


    the inlet is a Luer lock connector, the outlet is a Luer sliding connector,

    It can be connected with a conventional medical socket syringe to facilitate the accurate injection of the filtrate into the micro bottle. It can also be directly connected with the needle of the 7725 valve, and the sample can be injected directly after filtration.


    Sample volume: < 100ml of liquid at a time (specifically, there is a big difference according to the impurities of the filtered liquid)

    Filter area: 4.3cm2

    Dead volume: <100ul

    Filtration pressure: <87psi

    Filter Membrane Types




    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 Choose:

    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.
