Product Description
FilterMAX™ Syringe Filters, Hydrophobic PTFE, 25mm, 0.22um, case of 1000
FilterMAX™ Syringe Filters, Hydrophobic PTFE, 25mm, 0.22µm (1000/cs)
Organic solvents chew through some membranes, and PTFE is the one that shrugs it off. FilterMAX hydrophobic PTFE filters give you the broadest chemical resistance in the syringe filter lineup, built for solvent-based samples, mobile phase filtration, and venting applications where an aqueous membrane just won't hold up.
No hidden fees, ever: case pricing is exactly what you see, and ground shipping out of our Maryland warehouse is always free.

FAQ
Will this work with aqueous samples? Not well without pre-wetting with alcohol first. PTFE is hydrophobic by design; for aqueous work, use our RC or PES filters instead.
Is the housing autoclavable? SPEC NEEDED, not confirmed on our sheet.
What's the pore size? 0.22µm, suitable for sterile-grade filtration and fine particulate removal.
Sample volume this handles? The 25mm size is best for roughly 10-100mL sample volumes.
Any solvents to avoid? Perchloric acid, methylene chloride under prolonged exposure, and high-concentration dioxane, DMF, or formic acid are known incompatibilities for PTFE membranes generally.
