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 now available in 0.5 µm pore size to meet NIOSH specifications.
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.
