Naturally hydrophilic membrane designed to wet out evenly and retain its superior strength during use in general filtration or medical assays.

Fisherbrand™ PTFE membrane is hydrophobic filter made of polytetra-fluorethylene laminated with PP layer.

Designed for easy handling and maximum safety in air filtration. Sartorius™ Midisart™ 2000 PTFE Air Filter entirely eliminates moisture breakthrough because of its inherently hydrophobic PTFE membrane reinforced with polypropylene gauze. Stepped hose barb connectors ensure a simple and secure hold.

Protect the vacuum source during aspiration with this membrane filter. Integra Biosciences™ Hydrophobic Membrane Filters are designed for use with VACUSAFE Aspiration Systems.

Flexible and durable for easier handling.   Cytiva Nylon Membranes are naturally hydrophilic, eliminating need for wetting agents and prewetting when filtering aqueous solutions.

Manufactured from high-quality polycarbonate film and track-etched for high pore size precision. Whatman™ Nuclepore™ Polycarbonate Hydrophilic Membrane Sheets combine high flow rates and chemical and thermal resistance with sharply defined pores, making them suitable for microscopy, cytology, parasitology, and certain air and oceanography analyses.

Fisherbrand™ Mixed Celluloses Esters Membranes Sterile Filters are composed of cellulose acetate and cellulose nitrate.

Fisherbrand™ Polyethersulfone Membranes features highly asymmetrical pore structure that offers effective loading capacity and high flow rate.

Fisherbrand™ Mixed Celluloses Esters Membranes Non-sterile Filters are composed of cellulose acetate and cellulose nitrate.

Suitable for Clarification and sterilizing filtration of biological fluids . Fisherbrand™ Cellulose Membranes filters are composed of pure cellulose acetate modified to offer researchers the lowest binding filters available.

Mixed cellulose esters (MCE) membrane, hydrophilic

Hydrophilic PTFE polymer membrane filter compatible with virtually all solvents, acids, and alkaline solutions. Omnipore™ Membrane Filters are biologically and chemically inert.

Hydrophilic PTFE polymer membrane filter compatible with virtually all solvents, acids, and alkaline solutions. Omnipore™ Membrane Filters are biologically and chemically inert.

Combines uniform pore structure with high flow and adsorption rates. Sartorius Cellulose Nitrate Membrane Filters are excellently suited for diagnostic kits. Non-sterile, hydrophillic filters in a variety of diameters and pore sizes are bulk-packed to save money and space.

Manufactured from high-quality polycarbonate film and track-etched for high pore size precision. Whatman™ 293mm Nuclepore™ Polycarbonate Hydrophilic Membranes combine high flow rates and chemical and thermal resistance with sharply defined pores, making them suitable for microscopy, cytology, parasitology, and certain air and oceanography analyses.

Provides clarification of corrosives, solvents, and aggressive fluids. Whatman™ PTFE Membrane Circles are particularly useful in HPLC analysis when solid particles can cause permanent damage to the column.

Hydrophilic PTFE polymer membrane filter compatible with virtually all solvents, acids, and alkaline solutions. Omnipore™ Membrane Filters are biologically and chemically inert.

Mixed cellulose esters (MCE) membrane, hydrophilic

Manufactured from high-quality polycarbonate film and track-etched for high pore size precision. Whatman™ 13mm Nuclepore™ Polycarbonate Hydrophilic Membranes combine high flow rates and chemical and thermal resistance with sharply defined pores, making them suitable for microscopy, cytology, parasitology, and certain air and oceanography analyses.

Provides a contrast background for epifluorescence and other microscopy applications. Whatman™ Cyclopore™ Polycarbonate Black Membrane Filters improve test sensitivity with low background fluorescence.

Suited for applications involving aggressive organic solvents, strong acids, and alkalis due to being chemically stable and inert. Whatman™ WTP Range PTFE Membranes are particularly suitable for preparing samples for HPLC analysis, air and gas sterilization.
