The Mixer Mill MM four hundred is ideally appropriate for cryogenic grinding.Sample material and grinding ball charge are placed within the screw-top
stainless steel grinding jars, that are then immersed in liquid nitrogen.After having cooled down sufficiently,
they are mounted within the quick-clamping device of the MM 400; this is the
grinding jars securely, even at very low temperatures.After a grinding time of solely a pair of - three minutes a very
homogenized sample is obtained.This procedure saves time and isparticularly economical attributable to the terribly low consumption of liquid nitrogen.
