Wholesale Sterile Syringe Filters for HPLC

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.

The filter construction facilitates exceptional loading capacity with fast flow rates. This prevents the build-up of back pressure typically caused by the blocking of an unprotected membrane.

Non-sterile Disposable Syringe Filters typically consist of a PP housing, which is often made from materials such as polypropylene. The housing contains a filter membrane, which is usually made of materials like PTFE, PVDF, PES, MCE, NYLON, PP, CA, etc. Non-sterile Disposable Syringe Filters are available in a variety of membrane choices, which determine the size of particles or contaminants that can be effectively removed. Available in 13 mm and 25 mm diameters and 0.22 μm and 0.45 μm pore sizes. The choice of pore size depends on the specific application, with smaller pores being used to filter out smaller particles and larger pores for faster flow rates with less fine filtration.

The syringe filter produced by Aijiren is often used to filter impurities in the reagents to be tested. After the impurities are filtered, the reagents can be sucked into the autosampler. If the syringe filter is not used, it may cause problems such as clogging the needle hole with impurities in the reagent.
