Description

PORTEF's main filter media is PTFE membrane, and PTFE membrane has the excellent chemical compatibiltiy among the membranes.
The pore size of PROTEF is from 0.1um to 1.0um in absolute grade, and it is natually hydrophobic. To make it hydrophilic, the pre-wetting method is available.
With its chemical compaitbity, PORTEF is used in more spcific appliations which other cartridge filter can't be in.
PORTEF is used in various industries such as concentrated acid and baseds filtration, RO/DI filtration, photoresists, serile tan venting, fermentation air applications, rinses and solvets filtratioin, etchants, bulk chemical, wet-etch system, sterile process for gases, etc.
