Nylon does not tolerate aggressive chemical sanitization
protocols. Nylon membrane cartridges are best sanitized with
1% hydrogen peroxide or 1% hydrogen peroxide and peracetic
acid. Various manufacturers use different concentrations of
active ingredients. Refer and adhere to the manufacturer’s
instructions for sanitizing nylon membrane..

ENM Filter Cartridges are designed to meet the special needs
of the electronics and high purity chemical industries. Able to
remove particles below the rated pore size of the membrane,
these cartridges are cost effective and exhibit superior retention.
They are often used for DI water, photoresists, developers, and
other compatible chemicals. Each cartridge module is pulse power
flushed until the rinse effluent reaches 18+ megohm‑cm, and less
than 3 ppb TOC. Each cartridge module is also individually tested
for integrity. Our design criteria and special procedures allow us
to provide the highest quality electronics grade cartridges.
