The very strong motor of the Pulverisette 11 (up to 1250 watt) and its special knifes, fitted with up to four blades, allow fast and gentle grinding of difficult samples with high fat, oil or water content such as meat, gummi bears, chocolate or also hard samples such as dishwasher tabs or toys. It is perfect for sample preparation in the fields of food stuffs or animal feed testing, pharmaceuticals and chemistry and many other applications.
Due to its modern touchscreen with colour display, the Pulverisette 11 enables fast access to all functions and the SOPs. The grinding time of the integrated stopwatch can be set in 0.5 second steps using a practical multifunctional dial.
By the push of a button you simply change from continuous operation to interval operation for pre-crushing of harder samples resp. for better homogenisation or to the reverse mode for better mixing of the sample without having to open the mill. The parameters for interval mode can beset freely in the sub-menu. The motor speed can be set from 2,000 to 10,000 rpm – making it possible to adapt the mill to the specific behaviour of each sample. The additional turbo boost function, with 14,000 rpm for up to 6 seconds, facilitates the grinding of sticky and fibrous samples.
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.
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.
All elements can easily be removed for cleaning.
