Choose a Preferred Membrane Characteristic:

Hydrophilic - Hydrophilic membranes must be used for most water-based filtration applications. Options include Cellulose Acetate and Glass Fiber, Nylon, PES and PVDF.
Hydrophobic - PTFE is an inherently hydrophobic membrane, excellent for filtration of highly acidic or basic samples and solvents.
