Retsch Knife Mill GRINDOMIX GM 200, complete with 1 litre grinding container of autoclavable plastic, standard lid and knife of stainless steel, 220–240 V, 50/60 Hz

For chemical and physical analytical methods such as AAS, NIR, ICP or XRF it is essential that the specimen is perfectly homogenized to an adequate degree of analytical fineness.

A reliable and accurate analysis can only be guaranteed by reproducible sample preparation. For these tasks RETSCH offers a comprehensive range of the most modern mills and crushers for coarse, fine and ultrafine size reduction of almost any material. The choice of grinding tools and accessories ensures that our instruments provide for contamination-free and reliable sample preparation prior to laboratory analysis.

RETSCH knife mills provide completely homogeneous and reproducible size reduction results in seconds so that representative samples can be taken from any location in the grinding container.

Function Principle

 

Two sharp, robust blades rotate in the center of the grinding container. Depending on the rotational direction, size reduction is effected with the blunt side (preliminary size reduction) or the sharp side (fine grinding). 
The knife is indirectly driven by a powerful motor of 900 W. A pre-selectable speed which is maintained electronically ensures optimum adaptation to individual application requirements as well as reproducible grinding results.
