Whatman Nuclepore® membrane filters with hydrophilic polycarbonate membranes

Nuclepore® track-etched hydrophilic membranes offer a highly defined pore size cutoff in the sub-micron range, enabling particle deformity measurement and capture of extremely small particles. These filters are suitable for a wide range of sample types and applications, including bioassays, cell biology, and environmental analysis.

• Track-etched for highly defined pore size and high pore density
• Treated with polyvinylpyrrodoline (PVP) to render it hydrophilic
• Low extractables, minimizing filtration sample contamination risk
• High chemical resistance and good thermal stability for a wide range of sample types
• Low, consistent ash and low tare weights
• Smooth flat membrane surface for high particle visibility

Cytiva's Whatman Nuclepore® hydrophilic membrane filter range is manufactured from high-quality polycarbonate film, which is track-etched for high nominal pore size precision. These sharply defined cylindrical micropores, combined with high flow rates and chemical and thermal resistance, make Nuclepore® filtration membranes suitable for a variety of samples and applications, including microscopy, cytology, parasitology, and certain air and oceanography analyses.
