Mixer mill MM 500 nano
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.
HIGH SPEED BALL MILLING WITH EASY OPERATION FOR BEST RESULTS
- Max. speed 35 Hz
- Horizontal oscillation causes strong impact effects for effective sample processing
- Up to 10 mm feed size and 0.1 µm final fineness
- 2 grinding stations for jars of min. 2 ml and max. 125 ml, adapter for 18 x 2 ml single use vials
- Steel jars can be precooled manually in liquid nitrogen
- GrindControl to measure temperature and pressure inside the jar.
- Aeriation lids to control the atmosphere inside the jar
- Bench top model, touch screen, easy jar clamping, jars can stay clamped for subsampling, storable SOPs and cycle programs, 4 different jar materials for dry and wet grinding
GRIND SIZES IN THE NANOMETER RANGE
- New jar design allows for optimized usage of jar volume also for wet grinding
- Final fineness < 100 nm possible thanks to maximized energy input at 35 Hz
- Less warming effects, thus grinding can usually be done without grinding breaks for cooling down
Result: You get your nano sample within the shortest time.
Nano grinding of 25 g titanium dioxide in a 125 ml grinding jar zirconium oxide with 275 g balls 0.1 mm, 30 ml 1% NaPO4 solution. A particle size of 90 nm was achievied after 120 minutes of grinding.
