PULVERISETTE 11 Knife Mill
The PULVERISETTE 11 silent knife mill is an ideal, industrial-grade laboratory mixer that enables rapid yet gentle grinding and homogenization of moist, oily, or fatty samples, as well as dry, soft, medium-hard, and fibrous materials—all in a matter of seconds. Equipped with a powerful motor (up to 1250 W) and a specialized four-blade knife, the PULVERISETTE 11 efficiently and delicately processes challenging samples with high fat or water content—such as meat, gummy candies, or chocolate—as well as harder items like dishwasher tablets or toys. This versatility makes it an invaluable tool for sample preparation across a wide range of sectors, including the food industry, animal feed testing, pharmaceuticals, chemistry, and many other fields.
