3M Zeta Plus EXT SP

3M™ Zeta Plus EXT SP Filters

The Zeta Plus EXT SP Series filter extends depth filtration capacity and extends protection of downstream membranes thereby extending filter life and lowering overall filtration costs.
Zeta Plus EXT SP Series is a family of advanced dual zone depth filters designed to provide optimal clarification of bioprocess, biological and pharmaceutical fluids.
Zeta Plus EXT SP Series filters 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.

Features / Benefits

• Increased throughput with better turbidimetric efficiency
• Enhanced protection of downstream membrane filters
• A complete particle retention range from coarse to fine
• Open grade EXT fi lters are designed for primary clarification or to replace centrifuges and TFF systems
• Consolidation of multiple filter stages resulting in lower processing costs

Operating Conditions

• Maximum Operating Temperature 82° C (180° F)
• Recommended Flush 54 lpm/m²

Typical Applications

• Clarification of mammalian cell culture process fluids (cell separation)
• Protection of downstream processes including membrane (0.2, 0.1 μm) filters, TFF systems and chromatography columns.
• Clarification of bacteria and yeast cell lysates
• Endotoxin and nucleic acid removal
• Clarification of colloidal and haze forming contaminants.
