Each subsample taken from any location in the grinding vessel is representative for the original sample. This should ensure an exact, significant analysis for a wide range of different materials, regardless of whether the sample is dry, moist, soft, medium-hard, fibrous or oily. 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. The sickle knife made of stainless steel is ideal for grinding especially fibrous, tough or sinewy samples. 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. For food-safe analysis and for verification of polymers the grinding vessel made of glass is available. For grinding oily samples and for BPA-free sample preparation, the grinding vessel made of Eastman Tritan Copolyester is recommended.
