Additional Information
Memtrex HFE-T filters may be sanitized with
compatible chemical agents. The filters must
not be autoclaved or steam sterilized.
GE certifies that the material contained in its
Memtrex HFE-T pleated filters meet U.S. FDA
requirements for food contact under the ap-
plicable regulations in 21 CFR. For further in-
formation, contact GE technical services.
Memtrex HFE-T filters meet the test criteria for
USP class VI-121°C Plastics.
Aqueous extracts from Memtrex HFE-T filters
contain less that 0.25 EU/ml. The filters typical-
ly exhibit low levels of non-volatile residues.
GE filter cartridges are designed and manu-
factured for resistance to a wide range of
chemical solutions. Conditions will vary with
each application and users should carefully
verify chemical compatibility. Please contact
your GE distributor for more information.
