Result 1

	Universal Cutting Mill PULVERISETTE 19 Speed 300-3000 rpm
Equipment:	rotor with V-cutting edges and fixed knives made of hardmetal tungsten carbide (WC) + sieve cassette: 0,25 mm trapezoidal perforation
Feed quantity:	50 g
Feed Size:	< 120 mm long
Grinding time:	< 2 min
Final fineness:	< 0,25 mm (fine powder)
Comments:	For a longer durability by grinding of higher amounts of sample, we recommend using a rotor with knives made of hardmetal tungsten carbide instead of hardened stainless steel. The stalk pieces use to have a length about 12 cm and a diameter < 1 cm. The complete sample amount got fed within 120 seconds. After grinding, majority of openings of the used sieve cassette remain free. For this, a grinding of higher amounts of sample is still possible. Only electrostatic charged sample use to remain inside the grinding chamber afterwards. Cleaning can be performed rapidly by vacuuming with a soft brush.
