Manufactured from high-quality polycarbonate film and track-etched for high pore size precision. Whatman™ 19mm 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.

Ensure quality control in routine microbiological filtering. Sartorius Nongridded Sterile Cellulose Membrane Filters are single-packed membranes used for colony counting, particle testing, microscopy and sterility testing. Choose between cellulose acetate or cellulose nitrate membranes in a variety of pore sizes.

Collect airborne microbes and viruses. Sartorius Environmental Air Monitoring Gelatin Membranes guarantee reliable and accurate results. They are sterile and water soluble with a high retention rate. Choose from a range of sizes in single-wrapped disposable filters with holders or packs of filter disks.

Ensure quality control in microbiological filtering. Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters, 0.45μm are single-packed membranes with colored grids for colony counting, particle testing and microscopy. The 0.45μm pore size is made in accordance with ISO 7704. Choose from two diameters and quantities in a range of filter/grid color combinations.

Combines high flow rates and thermal stability with very low adsorption characteristics. Sartorius Cellulose Acetate Membrane Filters are excellently suited for use in pressure filtration devices. Non-sterile filters in a variety of diameters and pore sizes are bulk-packed to save money and space.
