Knife Mill PULVERISETTE 11
The quietly operating Knife Mill PULVERISETTE 11 is the ideal laboratory mixer in industry quality for very fast and gentle comminution and homogenisation of moist, oily and fatty as well as of dry, soft, medium-hard and fibrous samples within seconds. The up to 1250 watt strong motor of the PULVERISETTE 11 and its special knife, fitted with four blades, grinds fast and gentle problematic samples with high fat or water content such as meat, gummi bears, chocolate or also hard samples such as dishwasher tabs or toys. This makes it a perfect all-rounder with many advantages for sample preparation in the fields of foodstuffs or animal feed testing, pharmaceuticals and chemistry and many other applications.
The specially curved knife blades of the PULVERISETTE 11 achieve with up to 56,000 cutting processes per minute, significantly faster a homogeneous sample than comparable instruments at the same grinding time and rotational speed. And in the reverse mode, the PULVERISETTE 11 enables a better thorough mixing if necessary.
Interfering contours on the inner wall of the grinding vessel force the sample material towards the middle of the vessel and thus ensuring an efficient thorough mixing during grinding. The result: a homogeneous sample within a narrow particle size range.
Each subsample which you take from any location in the grinding vessel is representative for the original sample and thus ensures an exact, significant analysis. And that for a wide range of different materials.

GRINDING VESSELS 1.4 LITRE
The grinding vessel made of autoclavable plastic PC is included. For cryogenic comminution and for the grinding of harder samples we also offer a grinding vessel made of autoclavable stainless steel 316L. Grinding vessels made of glass and Eastman Tritan Copolyester are also available.
KNIVES
The standard knife made of stainless steel can be used for comminution of nearly all materials due to its four blades and a well-conceived geometry. For comminution of especially fibrous, tough or sinewy samples, we recommend the knife with serrated blades made of stainless steel.
