Z series depth filters have been developed for applications demanding excellent filtration removal efficiency with maximum filtration throughput.

Due to the pronounced positive Zeta potential, these grades of filter sheets are particularly suited for adsorptive removal of negatively-charged particles from aqueous suspensions. As opposed to standard filter sheets,depth filter sheets with an adsorptive effect exhibit a considerably improved clarifying effect without a sacrifice in output.

The grades Z 200 and Z 400 are characterized by a high bacteria retention capability; provided that they are suitably conditioned, they are capable of removing endotoxins from aqueous solutions.

For endotoxin removal, see also special documentation on Depth Filter Supra EK 1P.

Z–Series adsorptive filter sheets are compatible with most solvents as well as acids and alkalis provided that their concentration is low
