compact and affordable – for small sample quantities less than 5 ml

(PresseBox) (Idar-Oberstein, ) The new Mini-Mill PULVERISETTE 23 manufactured by FRITSCH for extremely small quantities, operates anywhere, small footprint, grinds any sorts of solid materials. Attractive presentation, user-friendly and affordable.

The special field of the NEW Mini-Mill PULVERISETTE 23 of FRITSCH is the fine comminution of very small-quantities of dry laboratory samples or solids in suspension. For mixing and homogenisation of emulsions. Sample quantity up to 5 ml, max. sample feed size: up to 6 mm.

This mill is ideal for sample preparation, for example, for chemical analysis, chromatography, mass spectrometry or X-ray structural analysis. It cam also 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 precious materials.

The PULVERISETTE 23 is also specially suited for the assessment of biological samples and for cryo-comminution of deep freeze or refrigerated soft samples.

Method of operation:
A large sized d.c. motor converts the rotation to a vertical oscillation using a robust crankshaft drive. The oscillation of the grinding bowl at high amplitude and high frequency generates a particle-size reduction in the grinding bowl through the impact and additional friction generated between the grinding balls and the grinding bowl walls.

A significant increase in effectiveness over comparable grinders is achieved, by adapting the interior design of the spherical grinding bowl to optimize the size reduction principle.

Features of performance:
- smallest sample quantities < 5 ml
- operator friendly
- easy cleaning of the grinding elements
- rapid, reproducible grinding
- small grinding bowl volume
- low contact surface area with grinding elements
- quick fastening and release of the grinding bowl
- oscillation amplitude 9 mm
- adjustable and reproducible grinding time
- adjustable stress frequency
- compact and affordable

FRITSCH: Your specialist in the processing laboratory

FRITSCH is the world-wide leading manufacturer of instruments for sample preparation and particle size analysis in the laboratory. Since 87 years now, the company is concentrating on the three product groups and identified with the brand names of PULVERISETTE, ANALYSETTE and LABORETTE in research and industrial laboratories. The FRITSCH name is synonymous with technical competence and economical efficiency in all matters in the field of

milling - particle sizing - dividing

Because FRITSCH operates throughout the world, they have the unique advantage of vast experience in a wide variety of scientific disciplines which enables them to offer constructive solutions to ease problem solving. FRITSCH laboratory instruments ensure proven, extreme longevity, highest quality and innovative technology in combination with simple operation.

Here a short view of the FRITSCH instrument range:

Mills for analytical sample preparation
FRITSCH offers an entire range of instruments for crushing, grinding, fine-milling, mixing and homogenising of hard-brittle, fibrous, elastic to soft materials dry or in suspension. The FRITSCH variety of grinding mills includes different ball mills, planetary ball mills, cutting mills, rotor mills, jaw crushers enables an optimal adjustment of the grinding process to the sample material and the following analyse.

Sieve Shakers and Laser Particle Sizers for particle size determination
FRITSCH with their vast experience in the particle sizing field offers Sieve Shakers as well as Laser Particle Sizers in different version.
FRITSCH offers due to its equipment varieties for each special use and application a particle size measuring instrument, which uses the most modern laser technology or the well-tried and reliable sieving method and this with an unbeatable price-to-performance ratio.

Laboratory instruments for analytical sample handling
The FRITSCH instrument range also includes sample divider and feeder, because representative sample dividing of dry samples or suspension as well as controlled and uniform sample feeding for mills and other instruments are basic conditions for reliable and precise analysis.

In addition to the complete programme of laboratory instruments, FRITSCH also offers a comprehensive range of services with Workshops, product presentations with the FRITSCH-Mobile laboratory bus on your door step, test milling or particle size analysis of your sample at no charge and much more.

Please use our instrument search engine and our grinding report data base on the FRITSCH-Homepage under – sample preparation – solutions. Here you will find your suitable instrument as well as a comparative grinding report comparable with your application.

Make use of our decades of experience. We can facilitate your work substantially.
