The resulting membrane is a thin, translucent, microporous polyester film with a smooth, flat surface
Track Etch Polyester membrane is produced through a two-step proprietary manufacturing process that employs high quality standards throughout production. This unique process allows for increased control over pore size and pore density to ensure the physical properties of each membrane precisely fit customer specifications.
In the first step, thin polyester film is exposed to collimated, charged particles from a nuclear reactor. As these particles pass through the polyester material, they leave sensitized tracks. In the second step, the polymer tracks are dissolved with an etching solution to form cylindrical pores. Varying the temperature and strength of the etching solution, and the exposure time to it, produces precisely controlled pore sizes.
The resulting membrane is a thin, translucent, microporous polyester film with a smooth, flat surface containing pores of controlled diameter and number. The membrane has better solvent resistance than polycarbonate and captures all particles smaller that the precisely controlled pore size on its surface. Sterlitech PETE membrane is ideal for use when analyzing blood samples or particle analysis by microscopy.
