Syringe filters are ideal for filtering the sample solution before injection. These are usually membrane filters made of appropriate materials. They are also available as glass fiber filters or as membrane filters with glass fiber pre-filters in cases where a glass fiber filter is required in front of the membrane filter. When selecting syringe filters, the highest quality materials should be used as the sensitivity of the analytical method increases. These are specially tested for interfering substances. In addition, they guarantee a high batch consistency for steady, reliable analytical results.
Syringe filters from renowned manufacturers such as Whatman, Thermo Fisher, Macherey-Nagel etc. are available at Analytics-Shop. In addition, we offer our own brand of Altmann Analytics syringe filters as a high-quality and cost-effective alternative. Easily select suitable syringe filters to meet your needs by using the drop-down menus on the left.
In the second info box you will find more information on the products and a selection guide for syringe filters.
The properties of syringe filters made from different materials are very different. Therefore, the choice of the filter depends greatly on the chemicals used.
The following table provides an overview of the most common materials (incl. abbreviations) for syringe filters, the application areas as well as the chemical resistance of each synthetic.

 |  |  |
Polyvinlyde difluoride (PVDF) | Â |
- hydrophilic membrane |
 |  |  |
Regenerated cellulose (RC) | Â |
- hydrophilic membrane with very low adsorbtion |
 |  |  |
Glass fibre / regenerated cellulose (GF/RC) |
 | - syringe filters with prefilters are recommended for solutions with high particle loads or for highly viscous solutions - these filters combine a coarse glass fibre prefilter and a narrow-pored regenerated cellulose membrane as the main filter - the hydrophilic RC membrane is used for filtration of aqueous and organic-aqueous liquids, i.e. polar and medium polar sample solutions |
