Polycarbonate Track Etch (PCTE) Membrane Disc Filters, 8.0um, 13mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215633

Featuring a thin, translucent polycarbonate track-etched (PCTE) film with precisely defined 8.0um cylindrical pores, these 13mm membrane discs deliver controlled, surface-capture filtration for general filtration and cellular applications. The PCTE film is treated with polyvinylpyrrolidone (PVP) to render it hydrophilic, providing reliable wetting for aqueous samples while maintaining a smooth, flat, glass-like surface ideal for optical and microscopic analysis.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Hydrophilic surface: Treated with a PVP wetting agent so the naturally hydrophobic polycarbonate film readily wets with aqueous solutions.
• Precise cylindrical pores: An 8.0um track-etch process creates uniform, defined pores that capture all particles larger than the pore size on the membrane surface.
• Smooth, thin, flat structure: The translucent, glass-like surface is well suited to particle identification by optical and electron microscopy.
• Low protein binding: Minimizes sample loss and background interference during analysis.
• Resists chemical staining: Eases microscopic visualization and promotes consistent results.

Key Construction Characteristics

• Membrane material: Polycarbonate Track Etch (PCTE), white, not gridded.
• Format: 13mm diameter membrane disc.
• Sterility: Nonsterile.
• Pack: 100 per pack.

This membrane provides consistent flow control and reliable surface capture for liquids moving through the filter. Its low-extractable, low protein binding construction helps maintain sample integrity and keeps analyses clean for reproducible results.

• General Filtration The hydrophilic 8.0um PCTE membrane provides reliable surface-capture filtration of aqueous samples.
• Prefiltration The large 8.0um pore size makes it well suited to prefiltering heavily loaded samples ahead of finer downstream membranes.
• Microscopy Sample Collection The smooth, flat, glass-like surface supports particle identification by optical and electron microscopy.
• Blood Cell Separation Precisely defined pores assist in the removal of red blood cells from plasma in assay workflows.
• Assay Flow Control Uniform cylindrical pores deliver controlled flow of reagents through diagnostic assays.
• Cellular Filtration Assays The defined pore structure suits cellular-based filtration applications requiring high purity.
