Cytiva - PTFE Membrane Disc Filters

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.
