Syringe Filters
Syringe filters are an essential tool in laboratories for filtering and cleaning samples prior to analysis. They are placed on the tip of a syringe and remove particles or impurities from a liquid to prevent clogging of the analytical columns and extend the life of the analytical instrument. These filters are available in different pore sizes for different requirements. They are crucial for precise analytical procedures and help to increase the reliability and accuracy of measurements.
In the MZ-Analysentechnik GmbH range you will find syringe filters from manufacturers such as La-Pha-Pack, Thermo Fisher Scientific and GS-Tek. In addition to our online range, we also stock low-cost filters from international manufacturers. We will be happy to help you in your search for suitable filters!
Technical Data
The housings of syringe filters are usually made of high-purity polypropylene (PP) or polyethylene (HD-PE), which have high chemical stability and contain only very low levels of extractable substances. The filters are available in different sizes depending on the sample quantity to be filtered. The table opposite is intended as an aid to selecting the correct filter size.
| Filter Diameter | Recommended sample volume |
| 3 or 4 mm | <1 mL |
| 13 mm | 1 - 10 mL |
| 17 mm | 5 - 50 mL |
| 25 mm | 5 - 100 mL |
| 30 or 33 mm | 10 - 100 mL |
How do I choose the right membrane for my application?
The filter membranes are available in a variety of different materials. The choice of membrane depends primarily on the solvent and the sample. Different membranes show different stabilities with regard to the pH value or for aqueous and organic media.
- aqueous, mechanically demanding, alkaline samples → nylon
- aqueous, biological samples with high protein absorption → CA, nylon
- aqueous, biological samples with low protein absorption → PES, RC, CA
- organic solvents → nylon, PTFE
- semi-organic solvents → RC, CA, PTFE
- gaseous (also for strongly oxidising gases) → PTFE
