Mixer Mill (Net weight – 60 kg VARIO)

The Mixer Mill (Net weight – 60 kg VARIO) is a versatile bench-top unit which provides ultimate performance with maximum flexibility for your sample preparation process.
It is used for dry, wet and cryogenic grinding of small sample amounts with high throughput. The Mixer Mill (Net weight – 60 kg VARIO) can be equipped with screw-top grinding jars from 1.5 ml to 50 ml.

THE STRONG MIXER MILL FOR HIGH THROUGHPUT APPLICATIONS

• Max. speed 35 Hz
• Horizontal oscillation causes strong impact effects for effective sample processing
• Up to 8 mm feed size and 5 °m final fineness
• 6 grinding stations for jars of min. 2 ml and max. 50 ml, adapter holds up to 50 x 2 ml single use vials
• Steel jars can be precooled manually in liquid nitrogen
• Bench-top model, touch screen, storable SOPs and cycle programs, 7 different jar materials

FUNCTIONAL PRINCIPLE

The grinding jars of the Mixer Mill (Net weight – 60 kg VARIO) 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. Also, 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.
