The Fritsch Mortar Grinder PULVERISETTE 2 is the ideal universal grinder in the laboratory thanks to its special mode of operation for analysis, quality control and materials testing as well together with 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 ideally suited for mixing of solids or liquids and solids. With brief, reliably reproducible grinding and mixing times, it is loss and dust free. For final finenesses of between 10 and 20 μm, with a feed size of 6 – 8 mm and a max. sample quantity of up to 190 ml.
Well-conceived details for efficient working and quick cleaning: the mortar bowl and pestle of the PULVERISETTE 2 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. And the special Fritsch scraper kinematics ensure that the scraper can be fi ne-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. For perfect material feeding.
The PULVERISETTE 2 is ideally suited for cryogenic grinding, where the material to be ground is embrittled with the addition of liquid nitrogen. In this manner moist, fibrous or elastic samples such as tomatoes, rubber, synthetic resins or plants can be ground without problem in the stainless steel grinding set.
Mortar bowls and pestles for the PULVERISETTE 2 are available in 7 different materials for contamination-free sample grinding, for each application a suitable one with the best protection against undesired contamination.
