Cellulose Ester Filters (MCE) 37 mm and 25 mm

The 25mm or 37mm PTFE membrane is suitable for air monitoring and sampling in aggressive environments, gravimetric sampling and filtration of gases and/or organic solvents.

Its structural strength and ease of handling make it a reliable choice for a variety of applications. The low chemical background and extractable hydrophobic nature of PTFE membranes also make them ideal for sensitive, interference-free analysis.
