PERFECT HOMOGENISATION The diversity of foodstuffs with their often very different product properties represents a real challenge for food testing laboratories. Before the actual analysis, the sample materials, which can vary strongly with regards to hardness and moisture, need to be homogenised and reduced to a sufficiently small particle size. Retch’s Grindomix knife mills are the ideal tools to meet the complex requirements of sample preparation of food. The model GM 200 has proven itself for the homogenisation of smaller sample volumes of up to 700ml. For larger volumes Retch now offers the new Grindomix GM 300 with a grinding chamber volume of 5 000ml. The wide range of accessories allows for easy adaptation to the individual application requirements:

NewSize:Newsize 2018/05/23 5:56 AMsamples Page 1such as soup, the use of Liquid samples: When preparing liquid

Retch’s patented gravity lid with overflow channels provides the best results. The lid reduces the grinding chamber volume to the size required for thorough homogenisation of the sample. It is designed in such a way that it floats on the surface of the sample. Hard materials: When grinding very hard products such as feed pellets, for example, a stainless steel grinding container should be used to minimise wear. Pre-grinding of medium-hard samples: The GM 300 features a reverse mode, which is suitable for medium-hard materials such as peeled nuts or frozen vegetables. To preserve the blades, the material is first comminuted with the breaking bar on the back of the knife (in reversed direction), before it is pulverised by the blades.

Benefits: • Efficient size reduction of up to 4 500ml sample due to powerful 1.1kW motor • Pre- and fine grinding in one mill • All parts coming into contact with the sample material are autoclavable • Variable speed from 500 – 4 000rpm • Optional gravity lid for automatic reduction of grinding chamber volume • Memory for 10 Standard Operating Procedures ravii@metrohm.co.za
