For fine comminution of minimal quantities of dry laboratory samples or solids in suspensions. For mixing and homogenisation of emulsions. Input quantity up to 5 ml.
Well suited for sample preparation, such as in chemical analysis, chromatography, mass spectrography or x-ray structure analysis. Preparation of samples in genetic research, homogenisation of ingredients, preparation of extracts in forensic analysis, grinding of pigments and precious materials.
The PULVERISETTE 23 is also excellently suited for solubilising of biological samples and for low temperature comminution of frozen or chilled soft samples.
The rotation of a large direct current motor is converted into vertical oscillation movement via a lifting piston gear. Through oscillations of the grinding bowl of large amplitude and high frequency, comminution occurs in the grinding bowls due to the collision between grinding balls and the grinding bowl inner wall as well as through friction between the grinding balls and the grinding bowl inner wall.
In contrast to comparable mills, the ball-shaped grinding bowl inner wall is optimised for the comminution principle and achieves a significantly higher level of efficiency.
The standard equipment delivered with the Mini-Mill PULVERISETTE 23 does not include a grinding bowl or balls. Grinding bowls and balls are offered in 4 different materials so that contamination of the samples through undesired rubbing off from grinding parts can be avoided.
