CUNO Depth Filter Cartridges

Zeta Plus® Depth filters are composed of cellulose and diatomaceous earth, a positively-charged media which traps contaminants smaller than the rated port size via electrokinetic absorption. Zeta Plus® filters capture submicronic contaminants, yet still yeild high flow rates with low differential pressure.

ZetaCarbon® Depth Filter Cartridges

The activated carbon is made into ZetaCarbon filter media by the addition of cellulose fibers and a positively charged resin. This eliminates the use of bulk carbon that causes dust-related issues especially for operators. CUNO incorporates five standard types of activated carbon to cover a broad range of applications. These have been specifically selected for their properties to meet industry requirements. ZetaCarbon filter media are also available in different porosities so that solutions with different viscosity’s can be processed. All the CUNO ZetaCarbon filter media available meet the market requirements whether 21 CFR or USP Class VI plastics compliance is required, with the necessary traceability and documentation. Drug Master File (DMF) and further technical details are available in the Regulatory Support File for ZetaCarbon filter media.

Zeta Plus C Series Depth Filter Cartridges

Zeta Plus C Series filters are a family of advanced depth filters designed to provide optimal clarification of pharmaceutical, biological, bioprocess, cosmetic, and food and beverage fluids. Zeta Plus C Series filters are composed of inorganic filter aid, cellulose and a proprietary resin system that imparts a positive charge to the filter matrix, aiding its adsorption of negatively charged contaminants. Zeta Plus C Series filters are advanced cellulose based depth filtration media, designed to retain contaminants by both mechanical entrapment and electrokinetic adsorption. Zeta Plus C Series filter media is composed of high surface area filter aids embedded in a cellulose fiber matrix.

Zeta Plus LP Series Depth Filter Cartridges

Zeta Plus LP Series Filters are a depth filter composed of inorganic filteraid and cellulose, extremely low in extractables, and designed specifically for the pharmaceutical industry. The LP Filter Media is constructed with highly purified cellulose to minimize b-glucan extractables and false positive LAL test results. The positive charge exhibited by Zeta Plus LP Filter Media results in increased particle removal efficiency. The high contaminant capacity of the filter medium prolongs final filter life when Zeta Plus LP Filter Media is used as a prefilter. Exacting quality controls as sure maximum product performance for each production lot. Zeta Plus LP Filter Media is manufactured to procedures described in CUNO’s Drug Master file on record with the FDA. Zeta Plus LP Filter Cartridges are manufactured in accordance with a strict quality assurance program. Each media lot is tested for flow, density, charge capacity, organic and in organic extractables, and pyrogenicity (LAL Clot Tests). In addition, Zeta Plus LP Filter cartridge packaging is labeled with lot identification number to provide complete trace ability from the media batch to the finished product.

Zeta Plus Maximizer™ Depth Filter Cartridges

Featuring a new (patent pending) dual zone construction, Zeta Plus Maximizer Series filters significantly increase through put per unit area of filter media, while optimizing the desired effluent clarity. This unique construction allows for smaller filtration assemblies, faster batch processing, reduced Clean In Place (CIP), and improved process economics

Zeta Plus S Depth Filter Cartridges

3M Cuno Zeta Plus S Series filters are a family of advanced depth filters designed to provide optimal clarification of pharmaceutical, biological, bioprocess, cosmetic, and food and beverage fluids. Zeta Plus S filters are com posed of inorganic filter aid, cellulose and a proprietary resin system that imparts a positive charge to the filter matrix, aiding its adsorp tion of negatively charged contaminants. Zeta Plus filters are advanced cellulose-based depth filtration media, designed to retain contaminants by both mechanical entrapment and electrokinetic adsorption. Zeta Plus filter media is composed of high surface area filter aids embedded in a cellulose fiber matrix. During the manufacturing process, molecules carrying a positive charge are chemically bonded to the filter matrix permanently forming an interconnected filtration structure with positively charged electrokinetic capture sites. The resulting porous depth filter is a tortuous net work of charge-enhanced flow channels capable of removing bacteria, particulate, cellular debris and submicronic contaminants to a level which mechanical screening alone can not achieve.

Zeta Plus ZA Series Depth Filter Cartridges

Zeta Plus ZA Series filter media are a family of advanced depth filters designed to provide optimal clarification of bioprocess, biological and pharmaceutical fluids. Zeta Plus ZA filter medium is composed of pre-extracted inorganic filter aid, cellulose and a proprietary resin system that imparts a strong positive charge to the filter matrix, aiding its adsorption of negatively charged contaminants. This patented, premium grade medium has been specifically designed for processes that require a high degree of filtration and low metalion extractables.
