FRITSCH Industrial Grade Laboratory Knife Mill - Reproducible comminution of a wide range of sample

from FRITSCH Milling and Sizing

The quietly operating Knife Mill PULVERISETTE 11 is the ideal laboratory mixer in industry quality for 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 up to 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.
Fast cutting processes – perfect mixing – representative samples: 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.
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.
Cryogenic processing: Samples which are difficult to grind such as gummi bears, chocolate or plastic toys can be embrittled with liquid nitrogen for comminution directly in the grinding vessel made of stainless steel 316L. The sample material remains 100 % cold. Just select the special lid with the easily exchangeable single-use sieve insert – the reliable protection against contamination.
Variable speed settings: The motor speed can be set digitally - in increments of a hundred between 2,000 and 10,000 rpm – making it possible to adapt the mill to the specific comminution behaviour of each sample. The additional turbo function with 14,000 rpm for up to 6 seconds maximum facilitates the grinding of sticky and fibrous samples.
Easy cleaning: 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.
