RETSCH is active in the fields of homogenizing laboratory samples for analysis as well as particle size analysis of solid substances. On the basis of more than 100 years of experience we have developed into the leading instrument manufacturer in these technologies.
MILLING & HOMOGENIZING
For chemical and physical analytical methods such as AAS, NIR, ICP or XRF it is essential that the specimen is perfectly homogenized to an adequate degree of analytical fineness.
A reliable and accurate analysis can only be guaranteed by reproducible sample preparation. For these tasks RETSCH offers a comprehensive range of the most modern mills and crushers for coarse, fine and ultrafine size reduction of almost any material. The choice of grinding tools and accessories ensures that our instruments provide for contamination- free and reliable sample preparation prior to laboratory analysis.
SIEVING & FRACTIONING
Particle size distribution influences the physical and chemical properties of solids. Therefore this criterion is of highest importance in the context of science and quality control. Only if the size distribution remains constant, a steady product quality can be guaranteed, as the following examples show:
⦁ the strength of concrete depends on the particle size of the cement
⦁ the taste of chocolate is influenced by the fineness of the cocoa
⦁ the flow characteristics and solubility of washing powders depend on the fineness and particle shape of the basic materials
RETSCH sieve shakers, test sieves and evaluation software provide the key to easy, rapid, reproducible and, above all, accurate analyses.
