The Whatman™ Nuclepore™ Polycarbonate Track-Etched Membrane Filters are precision-engineered filtration membranes designed for highly accurate particle separation, sizing, and analysis. Manufactured using advanced track-etching technology, these membranes feature uniform cylindrical pores with tightly controlled diameters, ensuring a highly defined pore size cutoff—ideal for capturing and analyzing sub-micron particles.
Constructed from high-quality polycarbonate film and surface-treated with PVP (polyvinylpyrrolidone) for hydrophilicity, these membranes provide low protein binding, low extractables, and excellent chemical and thermal resistance, making them suitable for a wide range of biological, environmental, and analytical applications.
