Filtration membrane discs are thin, precut membrane rounds designed for high-throughput, and fast filtration of liquid and gas samples in air monitoring and analytical research. Choose from gridded and non-gridded discs, as well as a variety of materials including mixed cellulose ester, polycarbonate, PTFE, nylon and PVDF. Rely on Thermo Scientific™ Nalgene™ Membrane and Prefilter Disks to meet a wide range of laboratory filtration needs.
Rely on Thermo Scientific™ Nalgene™ Membrane and Prefilter Disks to meet a wide range of laboratory filtration needs. Used in conjunction with either single use or reusable hardware and filter holders, filter disks offer you flexibility and choice to fit many applications.
Recommended for majority of routine applications, this membrane is manufactured under strictly controlled conditions. Whatman™ Type WCN Cellulose Nitrate Membranes narrow pore size distribution for improved surface capture and analysis.
Whatman polyethersulfone (PES) membrane filters from Cytiva’s Life Sciences business are hydrophilic and stable in alkaline pH, making them suitable for biological samples and aqueous applications.
Reduces background fluorescence in support of epifluorescence microscopy. Whatman™ Nuclepore™ Black Polycarbonate Membrane Filters improve visibility and help to distinguish microorganisms from other particulates.
Use for analyses of airborne contaminants and other particles using optical or electron microscopy. Isopore™ Polycarbonate Membrane Filters have a smooth, glass-like surface for clearer sample observation. Available in a variety of pore sizes/flow rates, diameters and colors.
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.
Recommended when maximum recovery is important. Durapore™ PVDF Membranes: 0.45μ Pore Size provide high flow rates and throughput, low extractables, broad chemical compatibility and low protein binding. Available in diameters ranging from 13mm to 142mm.
Manufactured from high-quality polycarbonate film and track-etched for high pore size precision. Whatman™ 47mm Nuclepore™ Polycarbonate Hydrophilic Membranes combine high flow rates and chemical and thermal resistance with sharply defined pores, making them suitable for microscopy, cytology,...
