Ultradyne® Filter (PTFE Membrane, Hydrophobic) - Aggressive Chemical, Severe Process Filtration

PTFE membrane filters providing the utmost assurance of chemical resistance, durability and critical filtration performance in aggressive fluids.

Ultradyne^® absolute-rated polytetrafluoride ethylene (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.

What are the typical applications?

Ultradyne^® 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^® filter must be pre-wet by immersion in a suitable low surface tension fluid. The inherently hydrophobic Ultradyne^® filter is ideal for gas filtration applications that include:
