Equipment
The standard equipment delivered with the Planetary Mono Mill PULVERISETTE 6 classic line includes „safe lock“ clamping; however, it includes no grinding bowls or balls, which are available in 8 different materials and must be ordered as accessories. The voltage indicated in the order (100-120/200-240 V) is preset.
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.
Method of operation
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.
Features overview
Small grinding bowl volume for minimal sample quantities < 5 ml
Small contact surface with grinding tools
Quick grinding bowl fastening with tongue and groove clamping system
Oscillation amplitude 9 mm
Adjustable, reproducible grinding duration and adjustable loading frequency
Regulated oscillation frequency (15-50 Hz.)
Robust crankshaft drive
Integrated glass keypad
Maintenance-friendly
2-year warranty
