3M™ Zeta Plus™ ZB Series Filter Cartridge Z16E08AA120ZB08A, 16 in, 1/Case

3M™ Zeta Plus™ ZB Series Filter Cartridge Z16E08AA120ZB08A, 16 in, 1/Case

Recommended for secondary polishing cell clarification applications, such as DNA removal, in recombinant proteins, such as monoclonal antibodies, 3M™ Zeta Plus™ EXT Series Filter Cartridge with ZB Series Media minimizes hold-up volume and maximize product recovery, while providing a particle free permeate solution for downstream processing.

3M™ Zeta Plus™ EXT Series Filter Cartridge with ZB Series Media are optimized for secondary polishing applications during filtration of mammalian cell harvest fluids, clarification of high protein concentration feed streams and for optimal protection of downstream sterilizing grade membrane filters. 3M™ Zeta Plus™ EXT Series Filter Cartridge with ZB Series Media are composed of inorganic filter aid, cellulose and a resin system that imparts a positive charge to the filter matrix. The single use format reduces the need for cleaning validation and minimizes filtration set up time for biopharma process development scientists.

3M™ Zeta Plus™ EXT Series Filter Cartridge with ZB Series Media grade media consist of two distinct layers, or “zones” of filter media with the upstream zone more open than the downstream zone. This structure enhances the contaminant holding capacity of the filter media, since larger particles are trapped in the upper zone of the filter media and smaller particles are trapped in the lower zone, reducing premature plugging and extending service life.

3M™ Zeta Plus™ EXT Series Filter Cartridge with ZB Series Media are optimized for clarification of mammalian cell harvest fluids and for protection of downstream sterilizing grade membrane filters. Their strong positive charge provides enhanced reduction of negatively charged contaminants compared to a mechanical filtration mechanism alone. In solution cells, cellular debris, endotoxins, and nucleic acids (DNA, RNA) carry a negative charge. 3M's application of positive zeta potential to 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.

Regulatory Support
3M™ Zeta Plus™ filters with ZB media are manufactured in accordance with an ISO 9001 Registered Quality Management system. All filter components success fully passed the USP <88> Class VI Biological Reactivity Tests. Each filter includes certificate of quality and, to ease validation and regulatory submission. These filters are registered with the US FDA with a drug master file and a comprehensive regulatory support file is also available.
