Featuring a thin polycarbonate film with precisely defined cylindrical pores, these track etched (PCTE) membrane discs deliver absolute size separation at a 0.8um pore size in a 13mm diameter format. Each membrane is produced through a two-step process in which polycarbonate film is exposed to ion particles that create tracks through the film, then chemically etched to open precise cylindrical pores. The result is a thin, translucent membrane with a smooth, flat surface, treated with polyvinylpyrrolidone (PVP) for hydrophilic wettability. The membranes are supplied white, non-gridded, and nonsterile in packs of 100.
Key Polycarbonate Track Etched Membrane Characteristics
- Hydrophilic wettability achieved by treating the inherently hydrophobic polycarbonate with a PVP wetting agent for aqueous sample handling.
- Precisely defined cylindrical pores at an absolute 0.8um pore size capture particles larger than the pore size for accurate, reproducible separation.
- Smooth, thin, glass-like surface presents a planar face well suited to particle identification and optical analysis by microscopy.
- Low protein binding minimizes sample loss and supports consistent assay results.
- Resistance to chemical staining eases microscopic visualization of retained particles.
Key Construction Characteristics
- Membrane material: polycarbonate track etched (PCTE), hydrophilic.
- Diameter: 13mm, supplied as flat membrane discs.
- Format and color: white, non-gridded membranes, nonsterile.
- Pack: 100 membranes per pack.
The defined pore geometry and superior film strength maintain pore size and density under use, supporting precise particle retention and dependable flow control. The low-binding, low-extractable surface helps preserve sample integrity for clean, repeatable results across filtration and microscopy workflows.
