Syringe Filters for Chromatography

We carry both Millex® and Whatman® syringe filters, the two premier brands in syringe filters for chromatography. Our combined portfolio offers many different membranes and housings for use in a wide range of applications.

Syringe Filter Selection Guide for Chromatography

The presence of particles in chromatography samples can cause pressure build up in the system, leading to instrument shutdown. This is especially true in UHPLC, due to its small particle-packed columns and narrow bore tubing. Regardless of the application, this potential problem is easily eliminated by sample filtration.
