TefGold cartridges are manufactured from a membrane with uniform thickness, high pore volume, controlled pore size and designed for the removal of submicron organic and inorganic particulate matter. The overall characteristics of the membrane media ensure that particles equal to or greater than the rated pore size are retained on the membrane surface. The structural stability of the membrane media eliminates media migration and the release of particles smaller than the removal rating even under pulsing conditions.
Manufactured from a highly hydro-phobic Polytetrafluoroethylene (PTFE) membrane, TefGold cartridges are guaranteed to provide media integrity and high flow rates throughout their useful life. Combining exceptional resistance to chemicals with high thermal stability, TefGold cartridges are ideal for the most demanding microfiltration applications. Particularly suited for the filtration of aggressive chemical solutions including acids, alkalis, solvents and enchants,
TefGold cartridges can also be used for a wide range of sterile venting and the filtration of moist gases.
TefGold cartridges are constructed of a multi-layer of (PTFE) membrane and polypropylene support media, which are pleated and bonded together to optimize the filtration area while permitting efficient flow with low pressure drop.
Each TefGold cartridge, has an effective filtration area of 7.5 ft per 10” module. Overall cartridge integrity is achieved by the absence of glues, resins, bonding agents and wetting surfactants thus maintaining minimum levels of extractables.
TefGold cartridges are manufactured in a class 10,000 cloakroom.
Each TefGold clean cartridge is integrity tested and batch identified prior to shipping.
TefGold cartridges are available in either standard or ultra-clean, rinsed with 18mΩ water to provide rapid resistivity recovery rates.
TefGold cartridges may be steam sterilized in-line or autoclaves repeatedly at temperatures up to 250ºF
TefGold cartridges are available in single or multiple lengths of 10″, 20″, 30″ and 40″. Micron ratings are 0.1 , 0.2, and 0.45. TefGold cartridges, furnished with a wide range of end caps, gaskets and O-rings, are designed to fit existing filter housings without modifications.
