Knife Mill
PULVERISETTE 11
For adaptation to your special application we offer extensive accessories. A 1.4 l grinding vessel made of autoclavable plastic PC with a standard lid and the standard knife made of stainless steel are included in the basic price of the instrument. When ordering a deviating specification of the standard accessories, please specify the exact article number of the part to be replaced.
Since the grinding times of the PULVERISETTE 11 are so short so that your samples can be processed very fast, it is worthwhile to order several grinding vessels right away for parallel use.
Additional knives are available on request.

Explanations on hardness data
The freely adjustable Vario-Lid system made of plastic PP fulfils 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. Thus you always achieve a homogeneous sample in a narrow particle size range even for smaller
sample quantities and for difficult-to-grind materials. The Vario-Lid system is delivered as a standard with a reduction sample pusher for moist, liquid and viscous sample materials such as tomatoes, cucumbers or yoghurt. It automatically returns rising liquids during the comminution and can be used for most sample materials.
A reduction sample pusher can be ordered as an option for dry, solid samples under order no. 11.3189.16.

Knives for standard grinding vessels, grinding vessels made of stainless steel and Eastman Tritan Copolyester
The standard knife with four cutting edges of the PULVERISETTE 11 (included with the instrument) can be used for the comminution of nearly all materials. The specially curved knife blades achieve with up to 56,000 cutting processes per minute a homogeneous sample significantly faster than comparable instruments at the same grinding time and rotational speed. And in reverse mode, the knives enable a better thorough mixing if necessary.
