DESCRIPTION
PTFE membrane disc filters, a Pall Life Sciences product, are 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.
Ideal for filtration of gas and/or organic solvents.
