Sample preparation: Mills, Grinders
|
|
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
Equipment
The Universal Cutting Mill pulverisette 23 is delivered without grinding bowl and ball. Bowl and ball made of stainless steel (10 ml or 15 ml volume) must be ordered as accessories.
