Universal cutting mill with adjustable rotational speed of 300–3000 rpm – PULVERISETTE 19 large
The PULVERISETTE 19 large is our high-speed, universal cutting mill with a torque of 30 Nm. It is designed for grinding dry, soft to medium-hard samples, as well as fibrous materials and plastics, delivering reliable, reproducible results. It accommodates a maximum feed size of 120 x 85 mm and offers a throughput of 85 l/h.
With a rotational speed that can be adjusted in 100 rpm increments—ranging from 300 to 3000 rpm—you can tailor the grinding process to a wide variety of applications and specific sample types. The PULVERISETTE 19 large is also ideally suited for conducting tests for RoHS compliance. Its design prioritizes cleanliness, ensuring the unit is easy to clean and provides robust protection against cross-contamination. Technical Data
