Supplier: Merck

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: Cytiva (Formerly Pall Lab)

Good prefilter made from PP/PE for heavily particulateladen and viscous fluids. Can be used as separators between stacked discs in a single filter holder during serial filtration.

Supplier: Whatman products (Cytiva)

Nuclepore™ track-etched hydrophilic membrane filters offer a highly defined pore size cut-off in the submicron range, enabling particle deformity measurement and capture of extremely small particles. The membranes have sharply defined pores, high flow rates, and excellent chemical and thermal resistance. They are suitable for a variety of samples and applications, including microscopy, cytology, parasitology, and certain air and oceanography analyses.

Supplier: Cytiva (Formerly Pall Lab)

Nylon 6,6 membranes for fluid filtration in the pharmaceutical, biotechnology, electronics, food and beverage industries and for analytical applications. These membranes are very resistant to mechanical, chemical and thermal stress. They can be used in either direction, are inherently hydrophilic, have high flow rates, low pressure drops and very low extractables. Where appropriate, they can be steam sterilised without change in flow or pore size characteristic.

Supplier: Merck

Durapore® PVDF white membranes provide high flow rates and throughput, low extractables and broad chemical compatibility. Hydrophlic membrane binds far less protein than nylon, nitrocellulose, or PTFE membranes.
