Fritsch Milling and Sizing

- Model PULVERISETTE 2 - Mortar Grinder


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.
