With four sharp, robust blades and a powerful motor which can reach temporary peaks of 3 kW, 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. The GRINDOMIX GM 300 meets and exceeds all special laboratory and analytical requirements and is a professional device superior to any commercial household mixer.
Features - Efficient size reduction of up to 4,500 ml feed quantity due to a powerful 1.1 kW motor (peak power input >3 kW)
- Pre- and fine-grinding in one mill: cutting action in regular mode, grinding by impact in reverse mode, pre-grinding in interval mode
- All parts which come into contact with the sample material are autoclavable
- Perfect adaptation to application requirements by variable speed from 500 to 4,000 min-1 with an increment of 100 min-1
- Optional gravitation lid for automatic reduction of the grinding chamber volume
- 10 SOPs can be stored
- Grinding jar in plastic and stainless steel available

Read More | The mixer mill MM 500 nano is a compact, versatile bench-top unit which has been developed specially for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material within seconds. With a maximum frequency of 35 Hz, it generates enough energy to produce particles in the nanometer range. The The mixer mill MM 500 nano is a compact, versatile bench-top unit which has been developed specially for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material within seconds. With a maximum frequency of 35 Hz, it generates enough energy to produce particles in the nanometer range. The robust high-performance drive makes the mill suitable for long-term grinding processes up to 99 hours. Hence, the MM 500 nano is the first mixer mill in the market to provide a real alternative to grinding in a planetary ball mill – with more comfortable handling and less warming effects. - powerful grinding by impact and friction with up to 35 Hz
