Nuclepore™ track-etched hydrophilic membrane filters offer a highly defined pore size cut-off in the submicron range, enabling particle deformity measurement and capture of extremely small particles. The membranes have sharply defined pores, high flow rates, and excellent chemical and thermal resistance. They are suitable for a variety of samples and applications, including microscopy, cytology, parasitology, and certain air and oceanography analyses.

• Track-etched for highly defined pore size and high pore density
• Treated with polyvinylpyrrolidone (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 track-etched (PFTE) membrane 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.
