Selection and Precautions Before Using the Syringe Filter

Syringe filters are mainly used for filtering mobile phase and sample in chromatographic analysis. Impurities in samples and solvents can not only damage chromatographic instruments and columns, but also greatly affect the analytical results. Thus, syringe filters can protect the column and the chromatographic system from contamination and improve the sensitivity and accuracy of analytical results.
Syringe filters are widely used in drug analysis, food testing, environmental monitoring, protein removal, and sterility testing.
The nylon membrane of a syringe filter is suitable for the filtration of aqueous and organic solvents, such as the sample preparation of liquid and gas chromatography. It is characterized by high flux, low solubility, and good mechanical strength. The good physical properties of nylon can meet the demand for demanding test conditions.

Features of a syringe filter

1. Relatively uniform aperture;
2. High porosity;
3. No media shedding;
4. Thin texture and low resistance;
5. Fast filtration and minimal adsorption;
6. Low cost.

The shell of a syringe filter

1. High-pressure polypropylene (PP);
2. No leakage;
3. Save the tedious and time-consuming preparation work;
4. High-temperature resistance.
