A 11 basic Analytical Mill Batch mill for two grinding processes: Impact milling of hard, brittle or embrittled grinding materials with a stainless steel beater. This racket can be used to Mohs hardness 6 (included). Slicing soft, fibrous materials using a cutting blade (not included). - Moist and sticky ingredients can be crushed by adding water - Tefcel grinding bowl (PTFE, glass fiber reinforced) with stainless steel inlet (1.4571), useful volume 80 ml (included). This allows grinding material to embrittle with liquid nitrogen directly in the grinding chamber - grinding bowl 250 ml useful volume optionally available Technical data: Process type: batch Working principle: cutting / impact Motor power consumption [W]: 160 Motor power output [W]: 100 Speed ??max.
