Polycarbonate Track Etch Membrane Disc Filters, 0.2um, 142mm, Hydrophilic, Nonsterile, 20/Pk
GVS SKU: 1215215

Featuring a thin, translucent polycarbonate track-etched (PCTE) film with precisely defined cylindrical pores, this hydrophilic membrane disc delivers exact 0.2um surface filtration across a 142mm diameter. The membrane is produced through a two-step manufacturing process in which polycarbonate film is exposed to ion particles that create tracks, which are then chemically etched into precise, cylindrical pores, giving exceptional control over pore size and density. A polyvinylpyrrolidone (PVP) treatment renders the membrane hydrophilic for use with water and aqueous solutions without pre-wetting. Each pack contains 20 nonsterile white discs.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Hydrophilic surface: Treated with PVP for spontaneous wetting in aqueous solutions, eliminating the need for pre-wetting.
• Precise pore structure: Sharply defined cylindrical pores provide accurate size separation, capturing all particles larger than the pore size on the membrane surface.
• Low protein binding: Exhibits negligible adsorption and absorption of filtrate to help preserve sample integrity.
• Smooth, flat surface: Captures particles in a single plane, simplifying optical and electron microscopy and resisting chemical staining for easier visualization.
• High purity: Manufactured under Class 100 conditions to be exceptionally contaminant free with low extractables.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE) film.
• Diameter: 142mm disc format.
• Pore size: 0.2um.
• Sterility: Nonsterile.
• Pack: 20 discs per pack.

This membrane provides reliable, reproducible surface capture for demanding analytical and laboratory filtration. Its precise pore geometry and low non-specific binding help maintain sample integrity from clarification through microscopic examination. The durable polycarbonate film offers broad chemical resistance and thermal stability across a wide range of samples.
