Knife Mill Provides Homogeneous Samples

The knife mill Pulverisette 11 provides a homogeneous sample in a short time due to its design. Each subsample taken from any location in the grinding vessel is representative for the original sample and thus ensures an exact, significant analysis. That is for a wide range of different materials, regardless of whether the sample is dry, moist, soft, medium-hard, fibrous, or oily. Ideal for sample preparation in the fields of foodstuffs or animal feed testing, agriculture and forestry, biology, pharmaceuticals, and chemistry.

The standard knife made of stainless steel can be used for comminution of nearly all materials due to its four blades and geometry. For comminution of brittle, hard samples we recommend the sickle knife made of stainless steel. The sickle knife with serrated blades is ideal for grinding especially fibrous, tough or sinewy samples, such as fish, meat, asparagus, or bamboo.

Even with the 1.4-l grinding vessels there is a choice. In addition to the grinding vessel made of scratch-resistant polycarbonate, a grinding vessel made of stainless steel 316L for cryogenic comminution and for grinding harder sample materials is available. Or you can use the grinding vessel made of glass for food-safe analysis and for verification of polymers. For grinding oily samples and for BPA-free sample preparation, we recommend the grinding vessel made of Eastman tritan copolyester.
