Syringe Filters for HPLC and sample preparation | analytics
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 fibre filters or as membrane filters with glass fibre pre-filters in cases where a glass fibre filter is required in front of the membrane filter.

Water and acetonitrile were passed through polypropylene or PTFE syringe filters (as indicated in legend), then used 1:1 (v/v) to prepare the mobile phase for UHPLC. The system was run at 0.25 mL/min for 600 min with backpressure recorded every 50 min. DP represents total change in backpressure after 600 min. Research.
Syringe Filters – Glass, PTFE, PES, PP, Nylon, & More
As chromatography has become more sophisticated with smaller dimensions and higher pressures, minimizing particulates has become more important. Our HPLC syringe filters have been designed to minimize the buildup of particles during analysis. This helps minimize the possibility of instrument failure or shutdown while also maximizing your uptime.
