Polycarbonate Track Etch (PCTE) Membrane Filters, 0.08um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1222093

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined, cylindrical pores, this 47mm membrane disc delivers a 0.08um pore size for precise size separation in demanding analytical filtration. The polycarbonate base material is treated with polyvinylpyrrolidone (PVP) to render the membrane hydrophilic, allowing it to wet readily in water and aqueous solutions. Each disc presents a thin, translucent, glass-like surface that supports clear microscopic visualization. Supplied nonsterile, white, and not gridded in packs of 100.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Hydrophilic surface: PVP treatment lets the membrane wet readily for use with water and aqueous solutions.
• Precise, cylindrical pores: The track-etch structure defines an exact 0.08um pore size for accurate, reproducible particle separation.
• Low protein binding: The smooth polycarbonate surface minimizes nonspecific binding and sample loss.
• Microscopy-friendly: The thin, translucent, smooth film resists chemical staining and eases microscopic visualization of captured particles.
• Strong structure: The integral polycarbonate film provides superior mechanical strength for handling.

Key Construction Characteristics

• Membrane material: Polycarbonate Track Etch (PCTE).
• Diameter: 47mm disc format with a nominal thickness of 0.005 to 0.02mm (5 to 20um).
• Surface: White, not gridded, plain.
• Sterility: Nonsterile.
• Pack: 100 discs per pack.

This membrane provides consistent pore uniformity for predictable, reproducible filtration results. Its low-binding, translucent surface helps preserve sample integrity while supporting downstream microscopic analysis. The robust polycarbonate film stands up to routine laboratory handling.

• General Laboratory Filtration The 0.08um precise pore structure supports accurate particle separation across routine aqueous filtration tasks.
• High-Purity Filtration Low extractables and low protein binding make the membrane well suited to clarifying high-purity fluids.
• Blood and Cell Assays The hydrophilic, low-binding surface supports blood assays such as removal of red blood cells from plasma.
• Microscopic Particle Analysis The thin, translucent, stain-resistant surface enables clear visualization of captured particles under the microscope.
• Reagent Flow Control Uniform cylindrical pores provide consistent flow control of reagents through assay formats.
