Probst & Class Colloid Mills

Probst & Class (PUC), established in Germany in 1926, is a pioneer in process technology, best known for its colloid mills—robust machines designed for precise wet grinding, homogenizing, dispersing, and de-aeration of liquid to semi-solid products. Whether it’s fine emulsions in the cosmetics industry or particle size reduction for pharmaceutical suspensions, their engineering delivers consistent performance and high-quality results across a broad spectrum of applications.

Industries served include food & beverage, chemical, cosmetic, and pharmaceutical sectors, with modular systems that support everything from lab-scale testing to full-scale production. PUC machines are prized for their reliability, customizable configurations, and hygienic design, making them a go-to choice for companies looking to optimize consistency, throughput, and product integrity.

The brand’s legacy is one of precision German manufacturing, where decades of experience meet cutting-edge innovation. By maintaining a sharp focus on micro-comminution and emulsification, PUC empowers manufacturers to achieve finer results with greater control—backed by the kind of technical refinement that turns engineering into an artform.
