Plain white polyethersulfone membranes provide ultrafast filtration for a variety of applications

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

Manufactured from high-quality polycarbonate film and track-etched for high pore size precision. Whatman™ 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.

Flexible 2 or 3 port GL 45 connection cap system

Recommended for particle-removing filtration of water, aqueous solutions and solvents for analytical determination. Sartorius™ Polyamide (Nylon) Membrane Filters are white, non-sterile filters without grids. Choose from two pore sizes in four diameters. Bulk packed for space and cost savings.

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.
