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 control is a unique compact, versatile bench-top unit which has been developed to work in a temerature range from -100°C to + 100°C and thus either cool samples or heat them up while grinding. It is used for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material The mixer mill MM 500 control is a unique compact, versatile bench-top unit which has been developed to work in a temerature range from -100°C to + 100°C and thus either cool samples or heat them up while grinding. It is used for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material within seconds. With a maximum frequency of 30 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 control is the first mixer mill in the market to provide a real alternative to grinding in a planetary ball mill with special cooling options and with more comfortable handling - powerful grinding by impact and friction with up to 30 Hz
- pulverization of two samples down to the nanometer range < 0.1 micron
- multi-cavity jars 2x 25 ml or 4 x 10 ml available
- adapter for keeping 2 ml plastic tubes or 2 ml steel tubes available
- suitable for long-term grinding processes up to 99 h
- suitable for mechanochemistry applications
- 3 different grinding modes (dry, wet or cryogenic)
- memory for 12 SOPs and 4 program cycles
- Screw-Lock jars, pressure-tight up to 5 bar
GrindControl to measure pressure and temperature available - grinding under inert gas (optional)
- jar design allows full use of the volume, also for wet grinding
- jars remain conveniently clamped for periodic sample extraction or visual checks
