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.

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.
Subject to technical modifications and errors
The new knife mill GRINDOMIX GM 200 is the ideal instrument for grinding and homogenizing foods and feeds. It allows to process sample volumesup to 0.7 liters quickly and reproducibly.
With two sharp, robust blades and a powerful motor, it is ideal for homogenizing substances with a high water, oil or fat content as well as for grinding dry, soft and medium-hard products. A wide selection of lids and containers allows for adaptation of the mill to individual application requirements. The GRINDOMIX GM 200 meets and exceeds all special laboratory and analytical requirements and is a professional device superior to any commercial household mixer.
