3M Zeta Plus ZA

3M Zeta Plus ZA Series filters

Zeta Plus ZA media are a family of advanced depth filters designed to provide optimal clarification of bioprocess, biological and pharmaceutical fluids.
Zeta Plus ZA Series filter medium is composed of pre-extracted inorganic filter aid, cellulose and a resin system that imparts a strong positive charge to the filter matrix, aiding its adsorption of negatively charged contaminants.
This premium-grade medium has been specifically designed for processes that require a high degree of filtration and low metal ion.
Zeta Plus ZA filter medium offers unique advantages in contaminant removal because of its strong electro-kinetic properties.
In addition to the mechanical exclusion of particles by its depth loading feature, Zeta Plus ZA filter medium adsorbs contaminants too small for removal by mechanical straining.
Because most particles in suspension are negatively charged, virtually all contaminants can be removed with proper grade selection.
Economical, efficient removal of negatively charged contaminants such as cell debris, colloidal material,
