GVS PETE Membrane is made from a thin polyester film with a high density of solvent resistance.

It is ideal for use in blood assays or general filtration where chemically aggressive solvents may be used.

The membrane is produced through a two-step proprietary manufacturing process similar to that of the PCTE membrane.
In the first step, polyester film is exposed to ion particles that pass through the film. As the ions pass through the film, they create “tracks” where the polymer is damaged.

The beamed film is then exposed to a chemical solution which 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 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 larger than the precisely controlled pore size on its surface.

  • Smooth, thin, glass-like surface: for microscopic visualization
  • Low protein binding: ensures clean results
  • Pore Size Range: 0.2μm to 10μm


  • General Filtration
  • Precise filtration and prefiltration
  • Removal of red blood cells from plasma
