Polycarbonate Track Etch Membrane Filters, 10um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1212661

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, this 47mm membrane disc delivers a 10um absolute pore size for precise size separation across general and high-purity filtration. The polycarbonate film is treated with polyvinylpyrrolidone (PVP) to render it hydrophilic, producing a translucent white membrane with a smooth, flat surface that captures all particles larger than the pore size directly on top of the filter.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Hydrophilic surface: Treated with PVP wetting agent so the naturally hydrophobic polycarbonate readily wets out with aqueous samples.
• Absolute pore size: A precisely controlled pore size and density provide flow control and capture of particles larger than the rated pore size on the membrane surface.
• Low protein binding: Minimizes sample loss and analyte adsorption during filtration.
• Smooth, flat surface: Translucent film resists chemical staining to ease microscopic visualization and surface particle counting.
• Superior strength: The thin polycarbonate film offers robust handling characteristics for routine laboratory use.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE) film, white, not gridded.
• Diameter: 47mm disc format.
• Pore size: 10um.
• Sterility: Nonsterile.
• Pack: 100 membranes per pack.

This membrane maintains reliable surface retention and consistent flow control for precise size separation, protecting sample integrity through low protein binding and stain resistance. The uniform pore structure supports accurate microscopic analysis and dependable, repeatable filtration results.

Hydrophilic

• General Filtration The 10um hydrophilic PCTE membrane provides dependable general-purpose filtration of aqueous samples with controlled flow.
• Prefiltration Its open 10um pore size and high particulate capacity make it well suited to prefiltering heavily loaded samples ahead of finer membranes.
• Blood and Cell Separation The smooth surface and absolute pore size support separation of larger cells, such as removing red blood cells from plasma.
• Microscopic Particle Analysis The flat, translucent, stain-resistant surface captures particles on top of the membrane for clear microscopic visualization and counting.
• Reagent Flow Control Precisely defined pore size and density regulate the flow of reagents through assays.
• Size Separation Studies The absolute pore structure enables precise size separation of particles in research and quality control workflows.
