Structure and Use of Syringe Filter

The housing material of syringe filter uses high-quality sanitary polypropylene. The structure and design of syringe filter are precision and ensure smooth filtration. Meanwhile, the rationalization of inner space and extremely low residual rate of syringe filter reduce waste of samples.

In HPLC analysis, as the particle size of packing material in the chromatographic column is small, it can be easily jammed by contamination particles. As a result, the sample and solvent need to be filtered in advance to remove particles of pollutants and thus protect the instrument. The ion chromatography which is commonly used in the analysis of the environment also requires no import of inorganic pollutants in the pre-filtration of samples. As an important procedure in the process of pre-filtration, syringe filter can be used in the analyses of HPLC and IC.

One of the disadvantages of traditional filters is easy to burst. However, after specially designed, some of the syringe filters are able to bear the burst pressure of 7 bar. Usually, the edge of the syringe filter is with a screw thread to realize slip resistance. In the laboratory, the filter membrane with consistent quality and clear specification are used cooperatively. The former one is to ensure the consistency of the analysis result, while the latter one is to relieve trouble of confusion.
