Mills and Grinders
A Universal Mortar Grinder for Every Application
Mar 18 2021
Thanks to its special mode of operation, the Fritsch Mortar Grinder PULVERISETTE 2 is the ideal universal grinder in the laboratory for analysis, quality control and materials testing as well as for the mixing and homogenisation of pastes and creams on a laboratory scale. Its particularly gentle grinding by friction with almost no thermal load is ideal for the preparation of tablets in galenics. Using liquid nitrogen it also grinds difficult-to-mill samples with moist, fibrous or elastic structures. The PULVERISETTE 2 is also suited for mixing of solids or liquids and solids. With brief, reliably reproducible grinding and mixing times, it is loss and dust free. For a final fineness’s between 10 and 20 μm, with a feed size of 6 - 8 mm and a maximum sample quantity of up to 190 ml.
Easy setting and re-adjustment of the pestle pressure on the mortar wall guarantees perfect grinding. The essential downward pestle pressure on the mortar bowl can quickly and easily be exactly adjusted and read off on a scale for reliable reproducibility. The optimised Fritsch scraper kinematics, which are adjustable on three axes, ensure that the scraper is always perfectly fitted against the inner wall of the mortar bowl and to guide rising material toward the pestle. Manual re-adjustment also possible during the grinding process.
A large acrylic window and the grinding chamber is illuminated with long life LEDs to check the grinding process. Sample materials, liquids and additives can easily be added during the grinding process. The sturdy coating of the mortar bowl with its high-quality plastic frame is particularly robust, light and with a good grip.
The mortar bowl and pestle of the PULVERISETTE 2, which are available in 7 different materials for contamination-free sample grinding, lock in place securely thanks to their bayonet clamping with just one motion and are just as quickly removed for cleaning. The pestle pressure can also be easily adjusted during grinding. The special Fritsch scraper kinematics ensure that the scraper can be fine-tuned in height and depth and that the setting angle to the mortar bowl can be adjusted according to your material and application - all conveniently from the outside.
