Mitex™ PTFE hydrophobic membranes are unaffected by almost all liquids, including organic solvents, concentrated acids and bases, propellants, and cryogenic fluids. They are unbacked, but easy to handle, combining the convenience of a backed membrane with the versatility of a pure PTFE membrane.

Supplier: Sartorius

These membrane filters have high hydrophilicity and exceptionally low non-specific binding characteristics. These membranes are ideal for sample cleaning and protein removal and when high recovery of the filtrate solution is of primary importance.

Supplier: Merck

These PTFE white hydrophilic membrane compatible with all commonly used HPLC solvents. The membrane undergoes a special treatment process to remove any residual extractables, to provide clearer analysis results. They are widely used for HPLC mobile phase filtration, clarifying acids, bases and dilute protein solutions and isolation of RNA.
