Whatman Nuclepore (PCTE), 25 mm, PVP-Free (hydrophobic), 3.0 µm, 100/pk

Nuclepore track-etched membrane filters offer a highly defined pore size cutoff in the sub-micron range, enabling particle deformity measurement and capture of extremely small particles. These membranes come in a range of pores sizes and diameters and are also available in sheet format. Whatman Nuclepore membranes are suitable for a wide range of sample types and applications, including bioassays, microscopy, cytology, parasitology, certain air and oceanography analyses, cell biology and environment analysis. Available in both hydrophilic and hydrophobic varieties.

• Track-etched for highly defined pore size and high pore density
• Low protein binding and 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

Nuclepore track-etched polycarbonate membranes are manufactured from high-quality polycarbonate film and have sharply defined pore sizes, high flow rates, and excellent chemical and thermal resistance. The membranes have a smooth flat surface and exhibit very low levels of extractables.

The hydrophilic membrane filters are manufactured from high-quality polycarbonate film track-etched (PFTE) membrane for high nominal pore size precision and are treated with polyvinylpyrrolidone (PVP).
