Pulverisettes:
Mini-Mill "pulverisette 23"
|
 |
|
For
fine comminution of very small-quantities, dry laboratory
samples or solids in suspension. For mixing and homogenisation
of emulsions. Sample quantity up to 5 ml.
Typical fields of application:
Ideal for sample preparation, for example, for chemical
analysis, chromatography, mass spectrometry or X-ray structural
analysis. Can be used for preparing samples for genetic
research, for homogenising of active ingredients, preparation of
extracts in the forensic analysis and milling of pigments or
other precious materials.
Method of operation:
Vertical oscillations of the grinding bowl with high amplitude
generates a particle-size reduction through the impact of the
grinding ball and friction between ball and grinding bowl wall.
|
Features of performance:
- small grinding bowl volume (2 sizes) for very small quantities <5
ml
- Low contact surface area with grinding elements
- Quick fastening of the grinding bowl with slot-and-key clamping system
- Oscillation amplitude 9 mm
- Adjustable and reproducible grinding time and adjustable stress
frequency
- Regulated oscillation frequency (15-50 Hz.)
- robust crankshaft drive
- Membran keyboard
- Certified safety (CE mark) - Ease of maintenance with 2 year guarantee
