Description of Cellulose Acetate Syringe Filters
Cellulose Acetate Syringe Filters combine high flow rates and thermal stability with very low absorption characteristics, suitable for filtration of proteins and enzymes, sterilization of tissues, and culture media. Cellulose acetate membrane syringe filters have uniform pore size, no media shedding, thin texture, low resistance, fast filtration speed, and very little adsorption. 0.45 micron filter sterilization can be used to filter particles and bacteria of gas, oil, beverages, wine, etc., and can be used as a test for particles and bacteria.
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 contaminants be introduced in sample pretreatment. Syringe filters can be used in HPLC analysis and IC analysis. Filtering sample solutions is an important step in the sample pretreatment process.
