One of the most commonly used membranes; broad compatibility with aqueous and organic solvents, stable hydrophilic membrane, not suitable for highly acidic samples. Highly hydrophobic, PTFE membranes are chemically inert to most organic solvents, alkalis and acids. PTFE can be used as a breather filter for aqueous applications. Can be used with aqueous solutions only after use of a wetting agent (eg alcohol). Hydrophilic membrane with good solvent resistance; low UV absorbing extractables and low nonspecific protein binding. Hydrophobic membrane has wide chemical compatibility with organic solvents; low non-specific protein binding. Hydrophilic membrane with high flow rates (liquids), low protein binding, low concentrations of extractable substances. Hydrophilic membrane with high flow rate, high protein binding capacity (not suitable for biological samples). Not suitable for use with strong acids and alkalis Low protein binding, ideal for aqueous based samples; high protein recovery from filtrate; lower protein binding compared to PVDF. Larger porosity; able to remove large particulates without clogging. Membrane of choice for low nonspecific protein binding applications; Tissue Culture media filtration and general biological sample preparation. General laboratory filtration; filtration for most samples; HPLC samples. NOTE: Nylon binds protein, do not use when high protein recovery is desired. Suitable for filtation of aggressive solvents, bases and acids. Can be used as ventilation filter. General biological filtration; filtration of samples where high protein recovery is desired.
