P-11
Homogeneous shredding in seconds - from food to plastic with just one appliance
The FRITSCH knife mill P-11 is a powerful knife mill for the rapid comminution and homogenization of demanding samples in laboratories and quality control. With its extra powerful motor and standard 4-blade knife, the instrument is ideal for a wide range of materials - from moist, oily and greasy to dry, soft, medium-hard and fibrous samples.
Flexible adaptation to different materials
The motor speed can be precisely adapted to the specific shredding behavior of each sample in steps of one hundred between 2,000 and 10,000 rpm. With a maximum blade circumferential speed of 67 m/s and a blade diameter of 128 mm, the grinder processes feed sizes of up to 40 mm. The integrated turbo function with up to 14,000 rpm for a maximum of six seconds makes it much easier to grind particularly sticky and fibrous materials.
Cryo-grinding for temperature-sensitive samples
For challenging materials such as jelly babies, chocolate or plastic toys, the knife mill enables embrittlement directly in the grinding container with liquid nitrogen. This cryogenic function extends the range of applications to temperature-sensitive and elastic samples that are difficult to grind at room temperature. Depending on the material, a final fineness of less than 300 µm can be achieved.
Optimum homogeneity thanks to variable lid system
The freely adjustable Vario lid system reduces the grinding chamber volume to up to 540 ml. This allows you to achieve a homogeneous sample with a narrow particle size range even with smaller sample quantities or difficult materials - a decisive advantage for reproducible analysis results.
Four knife options for specific requirements
- Smooth standard knife made of stainless steel for universal applications
- Smooth stainless steel sickle blade for hard and brittle samples
- Serrated stainless steel sickle blade for fibrous, tough or stringy samples
- Serrated sickle blade with TiN coating for metal-free shredding
Contamination safety and process reliability
Single-use containers ensure absolute contamination safety between different samples. The integrated SOP generator enables up to 20 standard operating procedures to be saved for reproducible workflows. With an output of 1,250 watts (200-240 V) and compact dimensions of 32 × 43 × 48 cm, the 17.6 kg benchtop device is suitable for laboratory use in food and feed testing, pharmaceuticals, chemicals and other areas.
