OMICRON® PTFE PM2.5 Filters for Ambient Air Monitoring, 2.0µm, PP Support Ring, Datamatrix Code and Sequential Alpha Numeric, 46.2mm, 50/Pack (Cross Reference 7592-104 or PM2547050 or PT47DMCAN)

OMICRON PTFE Membrane Filters are engineered specifically for Particulate Matter (PM2.5) Air Monitoring as per environmental guidelines. These filters are ideal for gravimetric analysis and chemical characterization of airborne particulate matter collected from ambient air sampling. The filters consist of a hydrophobic polytetrafluoroethylene (PTFE) membrane laminated on rigid polypropylene support ring — ensuring excellent particle retention, dimensional stability, chemical inertness, and compatibility with automated filter handling systems.
