    Product Details
    • Proprietary single-use capsules combine with ergonomically designed holders for easy operation
    • Single or two-stage depth filtration in one filter holder allows filtrate to follow vertical flow path
    • Vertical orientation of holders and capsules requires a smaller footprint and saves floor space
    • Translucent plastic shell allows easy detection of the liquid level for real time monitoring of the filtration process
    • Solid core design with fully encapsulated shell eliminates the need for a stainless steel housing and post-filtration cleaning validation

    The Zeta Plus™ Encapsulated System Filter Capsules, EXT with ZB Media is designed to be incorporated into a larger system that includes a holder and a set of single-use manifolds. This system was developed by 3M Purification, Inc., in the quest for a single-use depth filtration solution that combines a number of ergonomic advantages with our proven depth filter media.

    Increased Filter Life, Lower Filtration Costs
    Zeta Plus™ EXT filter series with ZB media is our family of advanced dual zone depth filters that are positively charged and designed to provide superior clarification of bioprocess, biological and pharmaceutical fluids. Zeta Plus EXT filter media is designed to extend depth filtration capacity and protection of downstream membranes, while increasing filter life and lowering overall filtration costs. Additional benefits of the Zeta Plus Encapsulated System include reduced operator exposure to spent cartridges and process fluids, reduced filter replacement time, reduced cleaning validation and use of cleaning chemicals.

    The Zeta Plus EXT filter series with ZB Media in our encapsulated format is optimized for clarification of mammalian cell harvest fluids and for protection of downstream sterilizing grade membrane filters. The media's strong positive charge provides enhanced reduction of negatively charged contaminants compared to mechanical filtration mechanisms alone. In harvest solutions, cells, cellular debris, endotoxins, and nucleic acids (DNA, RNA) carry a negative charge. The positively charged resin we incorporate into the ZB filter media creates a filter matrix that enhances the capture of negatively charged contaminants for maximum filtration performance. The strong positive charge over a broad pH range makes these filters ideal for cell broth clarification and for protection of downstream membrane filters.

    We use two distinct layers, or "zones," of ZB filter media in our EXT Series filters (PDF, 316 Kb) with the upstream zone having a more open pore structure than the downstream zone. This structure enhances the contaminant holding capacity of the filter media, since larger particles are trapped in the upper zone and smaller particles are trapped in the lower zone, reducing premature plugging and extending service life. The two filter "zones" can be independently selected and combined to optimize performance.

    Encapsulating High Performance
    In order to facilitate effective monitoring of liquid levels during fill, filtration and finish, we incorporated a translucent plastic shell on our standard capsules that allows technicians an easy view of the liquid level without having to interrupt the process. Another time saving feature is our self-guiding locking mechanism that provides fast and reliable capsule-to-capsule connections when used in our Zeta Plus Encapsulated System holders.

    When faced with the challenges of filtration for the bioprocessing industry, where upstream cell culture clarification or downstream impurity removal is required, the Zeta Plus™ Encapsulated Systems meet this challenge and raise the bar with an ergonomic, space-saving design. Encapsulated holders and Zeta Plus Capsules combine in three distinct ways: a pilot system (Model 16EZA) that is ideal for larger scale-up studies, and two systems (Models 16EZB and 16EZC) that are designed for production scale biomanufacturing.

    Ergonomically Innovative
    Our encapsulated holders for production scale biomanufacturing Models 16EZB and 16EZC can be pivoted between horizontal and vertical positions and allow for fast and convenient loading and unloading at waist height. Additionally, our innovative design creates a minimal footprint during filtration and storage, minimal fluid spills during unloading, and full utilization of the filter media. Our largest holder, Model 16EZC, is a multi-round holder designed to incorporate two, three, or five rows of rotating capsules.

    Applications

    • Clarification of mammalian cell culture harvest
    • Protection of downstream processes including membrane filters and chromatography columns
    • Clarification of bacteria, yeast and insect cell lysates
    • Host Cell Protein (HCP), DNA, Virus and Endotoxin removal
    • Protein aggregate removal
    • Reduction of anti-foaming agents
    • Clarification of colloidal and haze forming contaminants
    Scalability
    3M Purification has preserved the lenticular filter design and vertical flow path on our Zeta Plus™ Encapsulated System filter capsules that has proven effective for cartridge based depth filtration systems. In addition to the large scale capsules featured above we have single-use Scale-Up Capsules that do not require holder and are ideal for media grade screening and filter sizing with smaller process volumes. When the large capsules are combined with these smaller scale capsules, the Zeta Plus Encapsulated Systems offer a completely single-use solution to process 100 ml to 25,000 L of liquid.
