وصف
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.
