Fast size-reduction and homogenisation to achieve representative samples

Sep 18 2019 Read 325 Times

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

Easy cleaning and safe operating due to professional quality

The special safety is ensured by the fastening of the knife with a bayonet lock and cannot come loose even if the sample material is very hard or the start-up speed is too high. Grinding vessel, lid and knife of the PULVERISETTE 11 can be cleaned easily in the dishwasher. Depending on the version, all parts which come into contact with the sample materials such as grinding vessel, lid and knife are autoclavable for sterile comminution. The laboratory mixer in professional quality is a safe investment in efficient working, reproducible results for reliable analyses and highest safety at the workplace.

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.

Variable speed settings and turbo function

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 facilitates the grinding of sticky and fibrous samples.

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.

Operation advantage: Save up to 20 SOPs

With the PULVERISETTE 11 you have the possibility to program and save up to 20 Standard Operating Procedures (SOPs). In each SOP you can save up to 15 grinding sequences. Via the integrated USB interface, all saved SOPs can be uploaded, exchanged and saved with the free SOP editor by laptop. With the software P-11Control, the mill can be controlled and the SOPs can be edited, saved and managed directly on the connected laptop. Revision-proof grinding reports can be created, archived quickly and easily with the integrated report generator.
