Polycarbonate (PCTE) membrane filters are clear, thin, microporous filters with a smooth flat surface and precisely controlled cylindrical pores.image076

The precise port size of the PCTE filters is achieved by exposing polycarbonate film to charged particles in a nuclear reactor which leaves tracks in the film. The pore density is controlled by the duration of time that the polycarbonate film is exposed to the charged particles. The tracks on the polycarbonate film are then dissolved in a chemical solution to form cylindrical pores.

Pore sizes are controlled by varying the temperature, strength and exposure time of the etching solution.

This filter offers several benefits when viewing surface samples with optical or electron microscopes.

PCTE filters eliminate the clearing steps in microscopy required when using mixed esters of cellulose filters. The unique manufacturing process results in an extremely narrow pore size distribution for accurate separation of samples by size. The PCTE filters do not stain, minimising background interference.
