Polycarbonate Track Etched Membrane Disc Filters, 0.03um, 25mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215057

Featuring a thin, translucent polycarbonate film with precisely defined cylindrical pores, these Polycarbonate Track Etched (PCTE) membrane discs deliver a 0.03um pore size across a 25mm diameter for high-purity and general filtration. The track-etch structure captures all particles larger than the pore size directly on its smooth, flat surface, and a polyvinylpyrrolidone (PVP) treatment renders the membrane hydrophilic for ready wetting in aqueous samples. Each pack contains 100 nonsterile discs.

Key Polycarbonate Track Etched Membrane Characteristics

• Hydrophilic surface: treated with polyvinylpyrrolidone (PVP) to wet readily with aqueous solutions.
• Precise cylindrical pores: a defined 0.03um pore size and controlled pore density support exact size separation.
• Surface capture: particles larger than the pore size are retained on the membrane surface rather than within a depth matrix.
• Smooth, translucent film: a thin, glass-like surface eases microscopic visualization and resists chemical staining.
• Low protein binding: minimizes sample loss during filtration of protein-containing solutions.

Key Construction Characteristics

• Membrane material: Polycarbonate Track Etched (PCTE).
• Diameter: 25mm disc format.
• Sterility: nonsterile.
• Pack: 100 discs per pack.

The track-etch manufacturing process maintains tight control over pore size and density so each membrane performs consistently from disc to disc. The smooth, low-binding surface preserves sample integrity and keeps background interference low for downstream analysis. These characteristics make the membrane well suited to applications where precise particle retention and high purity are required.
