Polycarbonate Track Etched Membrane Discs, 0.4um, 90mm, Hydrophilic, Nonsterile, 30/Pk
GVS SKU: 1215303

Featuring a thin, microporous polycarbonate track etched (PCTE) film with precisely defined cylindrical pores, these 90mm membrane discs deliver accurate surface particle retention at a 0.4um pore size. Although polycarbonate is naturally hydrophobic, the membrane is treated with a wetting agent to render it hydrophilic, making it well suited for blood assays, high-purity work, and general filtration. The result is a thin, translucent film with a smooth, flat surface that captures all particles larger than the pore size directly on the membrane.

Key Polycarbonate Track Etched (PCTE) Membrane Characteristics

• Hydrophilic surface: Treated with a wetting agent (PVP) so the otherwise hydrophobic polycarbonate film wets readily for aqueous filtration.
• Precise cylindrical pores: The track etch process produces straight-through pores with an accurate size cut-off, capturing particles larger than the pore size on the surface.
• Smooth, flat surface: The thin, translucent, glass-like planar surface supports particle identification by microscopy.
• Low protein binding: Minimizes nonspecific binding for clean, consistent results.
• Surface capture mechanism: Functions as a screen-type filter rather than a depth medium, providing predictable retention and flow.

Key Construction Characteristics

• Material: Polycarbonate Track Etched (PCTE) film.
• Pore size: 0.4um.
• Diameter: 90mm disc format.
• Sterility: Nonsterile.
• Pack: 30 discs per pack.

These membrane discs provide reliable, reproducible separation across general and high-purity filtration workflows. The uniform pore structure maintains accurate size cut-off and predictable flow, helping preserve sample integrity from collection through analysis.
