Company

Genesis

Being the only company worldwide with an exclusive focus on the analysis of particle size and particle shape we have been able to successfully develop and continuously extend our position over the past decades - based on our breakthrough innovation RODOS dry dispersion. This was possible with the help of best experts and technologies. The Sympatec employees encompass experienced particle specialists and internationally renowned developers in the field of particle technology.

Sympatec GmbH was founded in 1984 as the first spin-off of the Technical University of Clausthal. Together with strong particle knowledge, a dozen patents, encouraged by first orders and a venture capitalist – the Swiss RIETER Holding AG – a group of Clausthal scientists got on its way to develop the dry dispersion method for particle sizing stirring up the international market. Starting from a private Clausthal basement (Engineering office PANTUC | 1981 to 1988) Sympatec GmbH was established at the founding site of Machine Works Remlingen (MAREM | 1984 to 1990), which also was the first production site. General Management, Engineering Office, and customer-related departments such as Sales, After-Sales and Application Laboratory found a first home in the Technology Centre Clausthal (TECLA | 1984 to 2004). As a consequence of a management buy-out in 1988, the innovative measuring and dispersion systems for laboratory and process applications were developed, manufactured and shipped worldwide from our new production site at the business park Unternehmenspark Goslar (UPG | 1991 to 2004). Founded in Clausthal in 2004, the newly constructed Pulverhaus infrastructure embodies our pioneering spirit in a unique centre of excellence in Particle Technology. Our worldwide headquarters now unite strategic management and all business operations under one roof. Pulverhaus is brand home to all Sympatec instruments. It is located in the immediate vicinity of the Technical University of Clausthal, the first development site and place of origin.

The company founders

Kurt Leschonski studied mechanical engineering at the Braunschweig University of Technology and has received his doctor’s degree at Karlsruhe Technical University in 1965. Following a scientific stay at Loughborough University in England for two years Kurt Leschonski came via Karlsruhe Technical High School to Clausthal Technical University in 1971 in order to set up the Mechanical Process Technology. He significantly shaped the scientific community of particle analysis technique and was part of the initiators of POWTECH exhibition and PARTEC conference the actually most influential international congress in the field of particle analysis technology. Kurt Leschonski was awarded numerous prizes from the US, Germany and Japan, the first-class Merit Cross of the Federal Republic of Germany and the honorary citizenship of the town of Clausthal-Zellerfeld. In 1984, he was co-founder of the Sympatec GmbH together with Stephan Röthele and the Rieter Holding AG.

Hans Probst on behalf of the Rieter Holding AG venture capital donator was in 1987 as Chief Excutive Offices and Member of the Executive Board one of the founding shareholders. Rieter Holding AG is an internationally active Swiss industry holding headquartered in Winterthur and leading supplier of systems for short-staple spinning mills. In the meantime, they have developed new business fields, in particular in the area of acoustic insulation for the automotive industry.

After his studies of Mechanical Process Technology at the Karlsruhe University of Technology Stephan Röthele followed in 1972 his academic supervisor professor Kurt Leschonski to Clausthal Technical University, entrusted with the set-up of the Institute of Mechanical Process Technology as the chief engineer. His focus in the institute was on the research and development of particle size analysis. Numerous patents, publications, speeches and presentations highlighted his increasing commitment as developer and entrepreneur.The main subject was in the beginning plants for dry sorting, e.g. of pumice and grit, raw materials of car shredder systems as well as old tire and copper cable recycling plants. He developed a special expertise for dispersing and measurement systems for particle size analysis. In 1977, Stephan Röthele founded a company for patent exploitation, in 1980 the PANTUC engineering bureau and in 1984 - together with professor Leschonski and the Rieter Holding AG - the Sympatec GmbH. Already in 1985, he was awarded as first scientist the technology transfer prize of the Braunschweig chamber of industry and commerce. In the following year he received also the first technology transfer prize of the German Federal Minister for Education and Science in Bonn. Since then he was assigned with numerous honours and awards, including the conferment of the honorary doctorate of the Clausthal Technical University. For his merits in scientific and economic fields he was honoured with the Federal Cross of Merit in 2010.

Having successfully completed the initial product portfolio for particle size distribution analysis of dry powders applying laser diffraction spectrometry on the basis the system combination HELOS & RODOS in the laboratory, in the years to follow continuously additional new developments resulted. Today they attract attention amongst scientific communities as technological mile-stones as for instance the modular product range of sensors and dispersers. Sympatec defined and initiated the development of instruments, which adapt in an optimum way to products and processes and the resulting specific requirements. They can be applied in laboratory quality control and for control of the production process.
