Don’t compromise your quality control

The GRINDOMIX Knife Mills GM 200 and GM 300 set standards in food sample preparation. The cutting effect produced by the steel blades results in the perfect homogenization of samples with high water or oil content. The model GM 200 for sample volumes up to 700 ml has been completely revised and upgraded.

Thanks to new features like the powerful 1000 W drive and the innovative Boost function, the mill is able to homogenize even difficult samples like tough meat with skin or fibrous plants very quickly and efficiently. The new GM 200 is operated via a user-friendly 4.3’’ touch display with direct access to the MyRETSCH web portal and allows storage of 8 SOPs and 4 program sequences.

With the program sequences it is possible to save a combination of two grinding steps which is ideal for samples which require, for example, pre- and fine grinding by impact and cutting.



  • Thorough size reduction and homogenization of the entire sample material in seconds
  • Pre- and fine grinding in one mill
  • Variable speed up to 10,000 min-1 including Boost function with 14,000 min-1
  • For sample volumes up to 700 ml
