Polycarbonate Track Etched (PCTE) Membrane

Polycarbonate Track Etched (PCTE) Membrane

GVS Polycarbonate Track Etched (PCTE) Membrane is made from a thin polycarbonate film with precisely defined pores. It is ideally suited for use in cellular-based filtration assays as well as filtration applications where high purity is required. The membrane is produced through a two-step, proprietary manufacturing process that employs high quality standards. In the first step, polycarbonate film is exposed to ion particles that pass through it. As the ions pass through the film, they create “tracks” where the polymer is damaged. The beamed film is then exposed to a chemical that etches out the tracks creating precise, cylindrical pores. Pore density is controlled by the number of tracks per unit area, and pore size is controlled by varying the temperature, strength and time of exposure to the etching solution. This unique process allows for increased control over pore size and density to ensure the physical properties of each membrane precisely fit your specifications. The resulting membrane is a thin, translucent polycarbonate film with a smooth, flat surface. All particles larger than the pore size are captured on its surface.

GVS offers a unique solution for Legionella analysis following the new standard UNI EN ISO 11731. Our sterile gridded membranes are suitable for this test and give you the best performances. GVS offers the PCTE AOX Membrane with exceptionally low protein-binding/extractable levels and precisely defined pores. These AOX polycarbonate (PCTE) membranes are ideally suited for the detection of man-made pollution in groundwater and wastewater (organic halide adsorption determination).

Category:

To optimize the suitability of PCTE, we offer a variety of products with unique characteristics:
PVP (polyvinylpyrillidone)-treated for a hydrophilic membrane
AOX-certified for applications requiring extremely low extractables
Black-dyed membrane for staining applications
PVP-free for a hydrophobic membrane
Features:
Absolute pore size and density allows for precise size separation
Direct thickness and pore size measurements provide accurate characteristics
Smooth, thin, glass-like surface is suitable for microscopy and cellular applications
