Downstream Systems

ZETA Downstream Systems

ZETA supplies customised downstream systems for production, processing and refinement as well as purification and compounding of biotechnological products. Beginning from heterogeneous input materials, our systems apply the most advanced processes and techniques to achieve the highest possible product yields. As far as possible, we ensure that customers are not dependent on specific manufacturers of consumables, giving them more flexibility and better options to pursue cost efficiency in their production processes.

A high level of automation that provides for monitoring and control of all relevant parameters enables a reproducible process that reliably yields a product of the defined quality and also ensures the safety of personnel. In addition, ZETA develops semiautomatic filling solutions with container traceability and solutions for automatic equipment recognition at different docking points.
