Syringe Filter

syringe filter is a single-use filter cartridge. It is attached to the end of a syringe for use. Syringe filters may have Luer lock fittings, though not universally so. The use of a needle is optional; where desired it may be fitted to the end of the syringe filter.

A syringe filter generally consists of a plastic housing with a membrane that serves as a filter. The fluid to be purified may be cleaned by drawing it up the syringe through the filter, or by forcing the unfiltered fluid through the filter.

Forms

In scientific applications, the most common sizes available are 0.2 or 0.22 μm and 0.45 μm pores. These sizes are sufficient for HPLC use. The smallest known sterile syringe microfilter have pore sizes of 0.02 μm. Membrane diameters of 13 mm, 25 mm are common as well.

Our syringe filter body is made of  polypropylene . The filter membrane is PES,PVDF, PTFE, Nylon, or other treated products for specific purposes.

Application

Syringe filters may be used to remove particles from a sample, prior to analysis by HPLC or other techniques involving expensive instruments. Particles easily damage an HPLC due to the narrow bore and high pressures within.  Being relatively affordable, they may be used for general purpose filtration, especially of smaller volumes where losses by soaking up filter paper are significant.

Syringe filters are also available for the filtration of gases, and for the removal of bacteria from a sample.
