Centrifugal Mill processes without cross contamination.
Laboratory and Research Supplies and Equipment

Centrifugal Mill processes without cross contamination.

With high torque motor and cassette principle, Ultra Centrifugal Mill ZM 200 handles hundreds of samples per day without cross contamination. Size reduction takes place by impact and shearing effects between rotor and fixed ring sleeve. Two-step process ensures quick, gentle processing. Mill is suited for applications such as foods and feeds, spices, pharmaceuticals, fertilizers, powder coatings,...
