Ultradyne®
PTFE membrane filters providing the utmost assurance of chemical resistance, durability, and critical filtration performance in aggressive fluids.
Ultradyne® absolute-rated polytetrafluoroethylene (PTFE) membrane filters offer the highest level of assurance of chemical compatibility and filtration performance in aggressive chemicals, prolonged hot air service, and other severe process conditions. Ultradyne® filters’ PTFE membrane delivers superior flow rates and long service life. The highly porous membrane is inherently hydrophobic and offers maximum chemical compatibility with minimal extractables in a wide range of fluids and applications. Support components are all-polypropylene.

Ultradyne® PTFE membrane meets the critical demand for contamination control in the chemical, microelectronics, aerospace, biologicals, pharmaceuticals, food and beverage, and other industries. The Ultradyne® cartridge is designed for the removal of particulates, colloids, and microorganisms from aggressive solvents, highly corrosive chemicals, and gases. It is ideal for bulk and point-of-use filtration. Typical chemicals include:
- Highly concentrated acids
- Bases
- Alcohols
- Chlorinated and fluorinated solvents
- Esters
- Ketones
- Photoresists
- Etchants
- Photolithographic solutions
For aqueous solutions, the Ultradyne® PTFE membrane filter must be pre-wet by immersion in a suitable low surface tension fluid. The inherently hydrophobic Ultradyne® PTFE membrane filter is ideal for gas filtration applications that include:
- Compressed air
- Fermentation air
- Pressurized gases
- Tank venting
