Syringe Filters

A syringe filter is a single-use filter cartridge attached to the end of a syringe and used for filtering small amounts of liquid for research purposes. Syringe filters are commonly used in labs for fast and efficient filtering and purification of materials.

MilliporeSigma carries the two premier brands of syringe filter, Millex and Whatman. The combined portfolio offers different types of membranes and housings for use in a wide range of scientific applications in the lab or in the field. We offer the following syringe filter membrane types: cellulose acetate, PES, glass fiber, PVDF, hydrophilic PVDF, mixed esters, PTFE, hydrophilic PTFE, nylon, alumina based and others. Membrane housing options include polypropelene, PVC, modified acrylic, high-density polyethylene, and polycorbonate among others.

How Syringe Filters Work

Syringe filters work by drawing liquid through a compressed area (the syringe housing) and forcing it through the filtering membrane inside the syringe. The filtered liquid is then contained inside of the housing and can be used in field and laboratory applications. Since material can be filtered selectively it is an efficient and effective method for filtering materials in a lab setting.

There are many different types of filter membranes used in syringe filters, but the most common are PTFE, PES, PVDF, nylon or other membrane types.
