RETSCH MM 400 Mixer Mill
Developed specially for dry, wet, and cryogenic grinding of small amounts of sample. The MM 400 Mixer Mill provides powerful grinding by impact and friction, up to 30 Hz for up to 20 samples per run. The degree of mixing can be increased even further by using several smaller balls.
Manufacturer: RETSCH 207450001
DescriptionThe mixer mill MM 400 is a compact versatile bench-top unit, which has been developed specially for dry, wet, and cryogenic grinding of small amounts of sample.
The mixer mill MM 400 can mix and homogenize powders and suspensions in only a few seconds. It is also suitable for the disruption of biological cells as well as for DNA/RNA extraction. With its high performance and great flexibility, the MM 400 is a unique product in the market.
- Reproducible and efficient grinding, mixing, and homogenization in seconds
- Powerful grinding by impact and friction, up to 30Hz for up to 20 samples per run
- 3 different grinding modes (dry, wet, or cryogenic)
- Screw-top grinding jars for leak-proof grinding
- 9 SOPs can be stored
- Wide range of accessories are available, including various jar and ball sizes, adapter racks, grinding tool materials, and CryoKit
The grinding jars of the MM 400 perform radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jars and pulverize it. The movement of the grinding jars combined with the movement of the balls result in the intensive mixing of the sample.
The degree of mixing can be increased even further by using several smaller balls. If several small balls are used (e.g. glass beads) then, for example, biological cells can be disrupted. The large frictional impact effects between the beads ensure effective cell disruption.Applications:
