For universal grinding of hard, medium-hard, soft, brittle, fibrous, abrasive and temperature sensitive materials (dry or in suspension) to analytical fineness. For analysis, quality control and materials testing as well as for the mixing and homogenisation of pastes and creams on a laboratory scale. Also ideally suited for mixing of solids or liquids and solids as well as cryogenic grinding.
Areas of application
Pharmacy, foodstuffs, chemistry, mining and metallurgy, geology and mineralogy, glass and ceramics industry, agriculture and forestry.
Method of operation
Similar to a hand mortar, using pressure and friction, the pestle, with its large grinding surface, grinds the material against the walls and bottom of the mortar bowl. The mortar bowl is turned by a gear motor and drives the pestle with its freely rotating bearing through friction. Guaranteeing a particularly uniform and gentle grinding through friction, mixing or homogenisation of organic and inorganic samples with no thermal load – dry or in suspension.
Features overview
- Fast, uniform comminution
- Simple filling even during grinding
- Illuminated grinding chamber for optimum control
- Loss-free grinding thanks to closed grinding chamber
- Precisely adjustable pestle pressure and optimum scraper kinematics
- Removal and installation of mortar bowl and pestle requires no tools (bayonet quick catch)
- Reproducible pestle adjustment without tools even during grinding
- Preliminary comminution setting for coarse samples
- Easy cleaning through simple removal of pestle and mortar bowl
- 7 different materials for mortar and pestle for pure sample grinding
- Certified safety (CE mark)
- 2-year warranty
