The most commonly used syringe filter pore sizes are 0.22 um and 0.45 um syringe filters

Sterile syringe filters are small, disposable devices used in laboratory and medical settings to filter and sterilize liquid samples before they are injected or analyzed. These filters are designed to remove impurities, particulate matter, bacteria, and other contaminants from liquids, ensuring that the filtered solution is free from any potential sources of contamination. Sterile 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. Sterile 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.

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.

When filtering samples choose right membrane syringe filter is very important. If you choose wrong syringe filters your chromatogrpahy instrument will be failed, which can waste a lot of time and money since liquids are normally very expensive.
