3M™ Zeta Plus™ LP Series Filter sheet is our filtration media composed of inorganic filter aid, cationic resin and is designed to be low in extractables.
For high contaminant holding media, economical filtration and reliable particle reduction use 3M™ Zeta Plus™ LP Series Filter Sheet.
Our family of depth filters retains contaminants by a combination of mechanical entrapment and electrokinetic adsorption. LP media feature a positive charge that pulls out more negatively charged contaminants compared to a mechanical filtration mechanism alone, and feature high purity, pre-extracted cellulose providing lower β-glucan extractable levels.
These filter sheets are manufactured to meet the strict requirements specified in 3M’s Drug Master File (DMF) including product control and traceability. They meet the requirements of USP Class VI Biological Reactivity Tests and Certificates of Quality are included with every filter. Providing this vital compliance documentation and traceability eases validation and regulatory submissions.
