We developed Zeta Plus™ SP Series Filter Cartridges to provide optimal clarification of pharmaceutical, biological, bioprocess, and cosmetic fluids. They are constructed with Zeta Plus™ SP Series depth filtration media, composed of inorganic filter aid, cellulose and a resin system that imparts a positive charge to the filter matrix, aiding its adsorption of negatively charged contaminants.
Pharmaceutical-grade filters that exhibit high contaminant-holding capacity and provide economical filtration and reliable particle reduction
Retain contaminants by both mechanical entrapment and electrokinetic adsorption
Zeta Plus SP Series filter cartridge media is offered in a full range of scalable capsule and cartridge filter configurations, enabling pilot testing and scale-up using the same materials as in full-scale systems
They are composed of inorganic filter aid, cellulose and a resin system that imparts a positive charge to the filter matrix, aiding its adsorption of negatively charged contaminants. SP Media are manufactured to procedures prescribed in 3M Purification's Drug Master Files on record at the United States Food and Drug Administration (FDA). Zeta Plus SP series media are non-toxic in accordance with systemic injection testing.
