Wholesale Non-sterile Disposable Syringe Filter for Laboratory
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. 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.
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.

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.
