For heavy-metal-(iron-)free grinding we recommend to order the PULVERISETTE 14 with a lid and collecting vessel, PTFE-coated.
Grinding of soft samples
For both: heavy-metal-free and iron-free grinding of leaves, grain or soft foods, equip your PULVERISETTE 14 with a PTFE-coated lid and collecting vessel.
In addition, select a 12-ribs pure titanium impact rotor and a sieve ring with reinforced edges also made of pure titanium with a matching perforation for the desired final fineness.
Grinding of medium-hard samples
For both: heavy-metal-free and iron-free grinding of rice, wood, leather or plastics, equip the PULVERISETTE 14 with PTFE-coated lid and collecting vessel.
In addition, select a TiN-coated rotor and sieve ring. For feed particle sizes < 10 mm, use a 12-ribs rotor, for feed particle sizes < 5 mm, a 24-ribs rotor. A sieve ring with trapezoidal perforation ensures additional comminution.
