Polycarbonate Track Etch Membrane Discs, 0.1um, 19mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215056

Featuring a thin, microporous polycarbonate track etched (PCTE) film with precisely defined cylindrical pores, these 19mm hydrophilic membrane discs deliver a 0.1um pore size for high-purity surface filtration. The track etch process produces uniformly sized, straight-through pores that capture particles larger than the pore size directly on the smooth membrane surface, making the medium well suited to microscopy and particle identification. Each pack contains 100 nonsterile discs.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic surface: treated with a polyvinylpyrrolidone (PVP) wetting agent so the naturally hydrophobic polycarbonate readily wets out for aqueous filtration.
• Precise pore structure: cylindrical, track etched pores provide a narrow pore size distribution and well-controlled pore density for consistent, predictable retention.
• Surface capture: particles larger than the 0.1um pore size are retained on the membrane surface rather than within a depth matrix.
• Smooth, glass-like surface: the thin, translucent film provides a planar surface ideal for sample viewing by optical or electron microscopy with minimal background interference.
• High strength and low extractables: the polycarbonate film offers high tensile strength and exhibits negligible adsorption and absorption of filtrate.

Key Construction Characteristics

• Material: polycarbonate track etched (PCTE) film.
• Format: 19mm diameter membrane disc, plain (ungridded).
• Pore size: 0.1um nominal pore size.
• Thickness: approximately 0.005 to 0.02mm.
• Sterility and pack: nonsterile, supplied 100 discs per pack.

These membrane discs maintain consistent flow and retention across the filtration surface, supporting reproducible results in demanding analytical workflows. The clean, low-extractable polycarbonate film helps preserve sample integrity while the precisely defined pore structure ensures reliable surface capture for downstream analysis.

• Microscopy Sample Preparation The smooth, translucent surface and surface-capture pore structure make these discs ideal for collecting particles for optical and electron microscope examination.
• Particle Identification and Counting Uniform, precisely sized pores retain particles larger than 0.1um on the flat surface for accurate enumeration and analysis.
• High-Purity Filtration Low-extractable, contaminant-controlled polycarbonate film supports applications where filtrate purity is critical.
• Cellular-Based Filtration Assays The biologically inert, precisely pored membrane is well suited to cell capture and related laboratory assays.
• Clarification and Fine Particulate Removal The 0.1um pore size removes fine particulates from aqueous samples ahead of analysis.
