Mortar Grinder
PULVERISETTE 2
Please note: The standard equipment delivered with the Mortar Grinder PULVERISETTE 2 does not include grinding sets. Mortars and pestles must be ordered as accessories. For contamination-free sample grinding, select the grinding set of your Mortar Grinder from seven different materials – the appropriate pestle and scraper are also supplied. A grinding set made of stainless steel without a plastic frame is available, especially for cryogenic grinding using liquid nitrogen to embrittle the material to be ground.
Material | Main component of the material | Density g/cm³ | Abrasion resistance | Used for grinding material |
Agate | SiO2 | 2.65 | Good | Soft to medium-hard samples, metal-free grinding |
Sintered corundum | Al2O3 (99.7 %) | 3.8 | Fairly good | Medium-hard, soft, brittle samples |
Hard porcelain | SiO2-Al2O3 (40%) | 2.4-2.5 | Sufficient | Soft, fibrous samples |
Zirconium oxide | ZrO2 | 5.7 | Very good | Fibrous, abrasive samples |
Hardened steel | Fe - Cr | 7.9 | Good | Hard, medium-hard, brittle samples |
Hardmetal tungsten carbide | WC | 14.95 | Very good | Hard, medium-hard, abrasive samples |
Stainless steel | Fe - Cr - Ni | 7.8 | Good | Medium-hard, brittle samples, cryogenic grinding of moist, fibrous and elastic samples |
Grinding sets consist of a high centralised mortar bowl rimmed in a plastic frame, pestle and scraper. A grinding set made of stainless steel without a plastic frame is available, especially for cryogenic grinding using liquid nitrogen to embrittle the material to be ground.
