Engineered agitation systems for reliable mixing. GMP‑aligned, scalable performance.

ZETA mixing systems are designed for the demanding requirements of pharmaceutical and biotech production. Using magnetically coupled agitation technology, our solutions eliminate dynamic shaft seals while delivering reliable mixing performance across a wide range of vessel sizes and process conditions.

From gentle mixing for sensitive cell cultures to high-torque agitation for fermentation and powder incorporation, ZETA mixing systems are engineered to support consistent product quality and robust manufacturing.

Mixing technology for aseptic manufacturing. Eliminating seals, reducing contamination risk.

Magnetically coupled agitators eliminate the need for mechanical shaft seals, removing one of the most common contamination risks in sterile manufacturing. By transmitting torque through a magnetic coupling, ZETA mixing systems maintain a fully sealed process boundary while delivering powerful and reliable agitation. Our mixing technology supports a wide range of vessel configurations and process conditions.
