PTFE Membrane Disc Filters
Strong, Chemically Resistant Membranes
for Air Monitoring and Sampling in
Aggressive Environments
- Low chemical background permits highly sensitive, interference-free determinations.
- Ensures accurate gravimetric determinations with low tare mass.
- Zefluor™ membrane, available in 0.5 μm pore size.
- Ideal for filtration of gas and/or organic solvents.
- For air monitoring and sampling in aggressive environments.
- Supported membranes offer increased durability for hostile testing environments or acid aerosol monitoring.
- Teflo membrane offers unique PMP support ring for PM 10 and PM 2.5 dichotomous and other air sampling techniques.
- Ultimate in chemical compatibility for filtering harsh chemicals and HPLC mobile phases that destroy other membrane materials.
