Zeta Plus Maximiser

The new Zeta Plus® Maximizer™ EXT filter from CUNO extends depth fil­tration capacity and protects the downstream mem­branes thereby extending filter life and lowering overall filtration costs. Zeta Plus Maximizer EXT Series is a family of advanced dual zone depth filters designed to provide optimal clarification of bioprocess, biological and pharmaceutical fluids. Maximizer EXT 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. The two filter zones can be independently selected and combined to optimize perfor­mance.

Zeta Plus® Maximizer™ EXT filter from CUNO offers distinct benifits like

Increased throughput with better turbidimetric efficiency
Lower processing costs
Smaller filter assemblies
Consolidation of multiple filter stages
Enhanced protection of downstream membrane filters

Applications
Maximizer EXT filters with SP media are optimized for clarifica­tion of mammalian cell harvest fluids and for optimal protection of downstream sterilizing grade membrane filters. In addition, their strong positive charge provides enhanced removal of neg­atively charged contaminants. In solution, cells and cellular debris, endotoxins and contaminating nucleic acids (DNA, RNA) carry a negative charge. CUNO’s patented* application of posi­tive zeta potential to SP 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.

Example of Applications include:
Increased throughput with better turbidimetric efficiency
Lower processing costs
Smaller filter assemblies
Consolidation of multiple filter stages
Enhanced protection of downstream membrane filters
