Retsch ZM1 High-Speed Centrifugal Grinding Mill for Fine Particle Size Reduction

The Retsch ZM1 Grinding Mill is a high-speed centrifugal mill designed for rapid and precise grinding of a broad spectrum of materials including soft, hard, brittle, and fibrous substances. Operating at selectable rotor speeds of 10,000 RPM or 20,000 RPM, it facilitates efficient comminution and fine particle size reduction in laboratory research and bioprocessing workflows.

Key technical features include:

• Rotor-driven impact and shear mechanism against a ring sieve for uniform particle size control
• Versatile final particle sizes ranging from 0.04 mm to 3 mm depending on the installed sieve
• Comes equipped with a 0.08 mm sieve, enabling fine pulverization essential for molecular diagnostics and synthetic biology applications
• Built-in timer and on/off switch for operation control and reproducible processing
• Suitable for sample preparation in fields such as biotechnology, biomanufacturing, and pharmaceutical research

The ZM1 mill supports critical pre-analytical workflows by delivering consistent sample particle size reduction, which is fundamental for downstream processes such as nucleic acid extraction, gene editing, and biopharmaceutical production pipelines. It is widely adopted in laboratories specializing in molecular biology, cell imaging, and biomedical engineering, where precise and contamination-free grinding is paramount.
