Polycarbonate Track Etch Membrane Discs, 1.0um, 90mm, Hydrophilic, Nonsterile, 30/Pk
GVS SKU: 1215153

Featuring a thin, microporous polycarbonate film with precisely defined cylindrical pores, these hydrophilic Polycarbonate Track Etch (PCTE) membrane discs deliver a 1.0um pore size in a 90mm diameter format, supplied nonsterile in packs of 30. The membrane is produced through a two-step track-etch process in which polycarbonate film is exposed to charged ions that create tracks, and those tracks are then chemically etched into precise, cylindrical pores. The result is a thin, translucent membrane with a smooth, flat surface that captures all particles larger than the pore size directly on its surface.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic wettability: the naturally hydrophobic polycarbonate is treated with polyvinylpyrrolidone (PVP) to provide a hydrophilic membrane for aqueous filtration.
• Precise surface capture: the controlled cylindrical pores capture all particles larger than the 1.0um pore size on the membrane surface, supporting accurate size separation.
• Smooth, translucent film: the flat, glass-like surface is well suited to particle identification and microscopic visualization.
• Low protein binding: minimizes sample loss and background interference during analysis.
• Chemical stain resistance: resists chemical staining to ease microscopic examination of captured material.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE) film, treated with PVP for hydrophilicity.
• Format: 90mm diameter disc, white and not gridded.
• Pore size: 1.0um.
• Sterility: Nonsterile.
• Pack: 30 discs per pack.

The track-etch manufacturing process provides tight control over pore size and density, helping each membrane consistently meet its stated specifications. The smooth surface and low protein binding maintain sample integrity for downstream microscopy and analytical work. These attributes make the membrane a dependable choice for general filtration and precise particle capture.
