RETSCH instruments are used in science and industry for the sample preparation for a wide range of different analytical methods as well as for particle size analysis in the context of production control and quality monitoring.
RETSCH meets the ever-increasing demands in these fields with a clear product philosophy: "The whole is greater than the sum of its parts"
In accordance with this principle we not only use high-quality components, but also place great value on their perfect interaction. The results are instruments characterized by their superior technology and outstanding reliability for each individual application in sample preparation and particle size analysis. This philosophy is reflected throughout the whole range of RETSCH products, which are arranged in three segments:
How are nano particles produced? The “Bottom-Up” method synthesizes particles from atoms or molecules. The “Top-Down” method involves reducing the size of larger particles to nanoscale, for example with laboratory mills. Nano particles are produced by colloidal grinding which involves dispersion of the particles in liquid to neutralize the surface charges. Factors such as energy input and size reduction principle make ball mills the best choice for the production of nanoparticles.
