Retsch Grindomix GM300 Knife Mill

The Retsch Grindomix GM300 Knife Mill is a high-performance laboratory instrument, now available as a second-hand system, designed for efficient homogenization of diverse sample materials. Equipped with a specialized cutting knife system and a versatile 5000 ml grinding chamber, the GM300 ensures rapid and consistent preparation of completely homogeneous analytical samples. The mill's capacity allows for the processing of substantial sample volumes, such as an entire loaf of bread or a full pizza, in a single operation. Precise parameter settings and programmable features guarantee reliable analytical outcomes with minimal variation.

The GRINDOMIX GM300 distinguishes itself from conventional household mixers with its ability to adapt to a wide range of applications, facilitated by an assortment of lids and grinding chambers. It supports seamless grinding, driven by a robust 1.1 kW motor (with peak power exceeding 3 kW), making it capable of processing up to 4500 ml of material. The unit combines pre- and fine-grinding functionalities, utilizing cutting in normal mode, impact-based crushing in backward rotation, and interval mode for pre-grinding.

All components in contact with samples are autoclavable, ensuring superior hygiene and safety. Users can precisely adjust the grinding speed between 500 and 4000 min⁻¹, in increments of 100 min⁻¹, to suit specific applications. The optional gravity lid further enhances versatility by enabling automatic reduction of the grinding chamber volume. Up to 10 parameter sets (SOPs) can be stored to optimize repeatability and efficiency in various operational contexts. Supplied with a stainless steel grinding chamber, the GM300 offers dependable performance that meets the rigors of research and development environments.
