PM2.5 PTFE Air Monitoring Membrane Filter
PM2.5 PTFE air monitoring membrane filters are designed for PM2.5 air monitoring. These filters are produced from high-purity hydrophobic Polytetrafluoroethylene (PTFE) according to 40 CFR Appendix-L to Part 50 Reference Method for the Determination of Fine Particulate Matter as PM2.5 in the Atmosphere. The pore size is 2 µm and the diameter is 46.2 mm.
Each filter has chemically resistant polypropylene support rings which have sequentially numbered.
Features
- Produced from high-purity hydrophobic Polytetrafluoroethylene (PTFE).
- Each membrane is sequentially numbered.
- No particle shedding, high stability.
- High sensitivity, extremely low extractable.
