Polycarbonate Track Etch (PCTE) Membrane Discs, 5.0um, 13mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215630

Featuring a thin, microporous polycarbonate film with precisely defined cylindrical pores, this hydrophilic Polycarbonate Track Etch (PCTE) membrane disc delivers accurate surface capture and reliable size separation. With a 5.0um pore size and a 13mm diameter, it captures all particles larger than the rated pore size on its smooth, flat surface, making it well suited to high-purity and general filtration work. The membrane is supplied nonsterile in a pack of 100.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Treated with a wetting agent (PVP) to make the naturally hydrophobic polycarbonate film hydrophilic for aqueous sample handling.
• Precise, cylindrical pores formed by a two-step track-etch process provide accurate size cut-off and surface particle capture.
• Thin, translucent film with a smooth, flat surface that resists chemical staining and eases microscopic visualization.
• Low protein binding supports sample integrity in assay and analytical workflows.
• Captures 100 percent of particles and cells larger than the rated pore size on the membrane surface.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE), hydrophilic.
• Pore size: 5.0um nominal, with a 13mm membrane diameter.
• Format: White, non-gridded membrane discs.
• Sterility: Nonsterile, supplied 100 per pack.

The defined pore geometry maintains accurate particle separation and consistent surface capture across samples. The smooth film surface supports clear optical and microscopic evaluation while protecting sample integrity. These discs provide dependable performance for general and high-purity filtration applications.

• General Filtration Delivers reliable surface capture of particles larger than 5.0um for routine high-purity and general-purpose filtration.
• Microscopy and Particle Counting The smooth, flat surface retains particles on top of the membrane for clear visualization and accurate counting.
• Prefiltration Captures larger particulates to protect and extend the life of finer downstream membranes.
• Blood and Cell Studies Hydrophilic polycarbonate film suits blood assays and separation of cells larger than the pore size.
• Sample Clarification Removes coarse particulates from aqueous samples ahead of analysis.
