3M™ Zeta Plus™ EXT BC Filter Capsule with SP Series Media
Filters Membrane Filter Capsules
The Zeta Plus™ EXT series media extends depth filtration capacity and protection of downstream membranes thereby extending filter life and lowering overall filtration costs.

  • Increased throughput with high turbidimetric efficiency
  • Enhanced protection of downstream membrane filters
  • A complete particle retention ranges from coarse to fine
  • Open grade EXT filters are designed for primary clarification or to replace centrifuges and TFF systems
  • Consolidation of multiple filter stages resulting in lower processing costs
  • Nominal rate (porosity): 0,8 to 5 µm

Zeta Plus™ EXT series 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.

Zeta Plus™ EXT series with SP and ZB media are optimised for clarification of mammalian cell harvest fluids, clarification of high protein concentration feed streams and for optimal protection of downstream sterilising grade membrane filters. Zeta Plus medias are composed of inorganic filter aid, cellulose and a resin system that imparts a positive charge to the filter matrix. ZB media shows a higher anion capacity than SP media.

Maximum operating temperature:
- BC25 capsules and 170 Scale-up capsules: 40 °C

Minimum required preconditioning flush:
- BC25 capsules: 54 L/m² with water or other suitable fluid at a volumetric flow rate up to 210 L/m²/hr

Sterilisation parameters:
- BC25 capsules: Autoclave 30 minutes at 121 °C (250 °F) (1 cycle)

Zeta Plus™ EXT series is available in autoclavable and fully disposable BC25 and in Zeta Plus™ encapsulated system capsules. With 25 cm² (99,06 mm²) of filtration area, the ready-touse BC filter capsule is ideal for feasibility and sizing trials. The Zeta Plus™ encapsulated system includes capsule filters with effective filtration areas at 170 cm², 340 cm², 1020 cm², 0,23 m² and 1,6 m². They are ideal for both the scale-up studies as well as large scale production.
