Air Monitoring Devices & Tubes

Quality air monitoring products for the detection and measurement of exposures to gases, vapors and particles in ambient, indoor air and workplace environments. Our range of products include active, passive and whole air sampling devices; air sampling pumps and related accessories.

Sterile and Nonsterile Millex® Syringe Filters
Millex® Syringe Filters

Millex® syringe filters are available in sterile and nonsterile formats, offered in many membrane and housing options to enable compatibility with multiple solvents and sample types for applications including HPLC, UHPLC, and dissolution testing. 

U-shaped purge trap
Purge & Trap

The purge and trap method is applied for the analysis of volatile organic compounds (VOCs) in aqueous samples by purging the sample with inert gas and transferring volatile analytes to an adsorbent trap in a gas chromatograph (GC).

Nitinol-core SPME fiber
Solid Phase Extraction & QuEChERS

Products include cartridges, glass tubes, 96-well plates, QuEChERS tubes (dispersive SPE), online SPE, and vacuum manifolds for all of your scientific needs.
