Whatman Nuclepore Hydrophilic Membrane, 0.4 µm pore size, 25 mm, circles, 100/pk
Tracketched 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
Nuclepore tracketched hydrophilic membrane filters offer a highly defined pore size cutoff in the submicron 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, cell biology and environment analysis.
Hydrophilic membrane filters with sharply defined pores
Cytiva's Whatman Nuclepore hydrophilic membrane filter range is manufactured from highquality polycarbonate film tracketched (PFTE) membrane for high nominal pore size precision.ophilic membrane filters with sharply defined pores. 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.
