Fritsch® Rotor p-19 chromefr. wkz-steel w. V-cutting edges + set counterm.

this rotor with V-cutting edges and counter-knives made of chromium-free tool steel grinds the specimen gently by pure cutting action. Alternatively, a rotor with straight cutting edges and counter-knives made of chromium-free tool steel is also offered, which also gently comminutes the sample by pure cutting stress, but can only be used for material that can be cut well and does not enable as effective comminution as the rotor with V-cutting edges. The rotors made of chromium-free tool steel are especially recommended for sample preparation according to RoHS and WEEE (e.g. for the detection of hexavalent chromium) and for XRF analysis. For all other applications, we recommend our cutting tool sets made of tool steel and carbide tungsten carbide, as these are harder and thus more resistant to abrasion.
