Filtration Membrane Discs

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.

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.

Whatman™ Mixed Cellulose Ester Membrane Filters are biologically inert and offers high degree of internal surface area for greater product adsorption.

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

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.

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

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.

Used in analytical research.

Hydrophobic membrane with laminated backing for easier handling

MF-Millipore™ Membrane Filter composed of mixed cellulose esters (MCE) membrane, hydrophilic.

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.

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

Useful for most filter applications

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,...
