Description and Use

Memtrex FE-S (MFE-S) filters (Figure 1) are sterilizing

grade cartridge filters for use in validated applica-

tions. The commitment to validation by GE Water &

Process Technologies is based upon the FDA Guide-

lines that we "establish documented evidence of

assurance that a specific process will consistently

produce a product meeting its predetermined

specification and quality attributes."

A detailed Validation Guide is available from GE to

document our rigorous testing for your records

and reviews. The guide includes all the data neces-

sary to assist the user with compliance to regula-

tory requirements.

The inherently hydrophobic MFE-S filter is just one

example of our strong commitment to the pharma-

ceutical industry. Our complete portfolio includes

filters for every stage of processing, and we offer

custom solutions for your unique applications. GE is

your complete source for filters, crossflow mem-

branes, housings and other filtration equipment.
