Knife Mill PULVERISETTE 11 in standard configuration

The Knife Mill PULVERISETTE 11 provides a homogeneous sample in a very short time due to its special design. Each subsample taken 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, 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.

For Each Application the Perfect Accessories

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 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 litre grinding vessels you have the 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 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. 

Configure your Knife Mill PULVERISETTE 11 suitable for your specific application.

Different knives with 4 blades – up to 56,000 cutting processes per minute

Autoclavable Vario-Lid system

The freely adjustable Vario-Lid system fulfills two important requirements at the same time. It can be used to reduce the grinding chamber volume down to 0.54 litre and to manually compress and loosen up the sample material at the beginning and at any time during comminution.

Easy cleaning – especially safe

Grinding vessel, lid and knife of the PULVERISETTE 11 can be cleaned without a problem in a dishwasher. Depending on the version, all parts which come into contact with the sample materials such as grinding vessel, lid and knife are autoclavable.

Fast cryogenic comminution in a single step

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.
