When ultra-clean materials are the ultimate
Our products for analytical and medical technology
Ultrapure materials in safe, accurate and durable products
Our ultra-pure graphite and carbon materials play out their unbeatable advantages wherever exact measurement results, long-term stable material properties and absolute reliability are required - for example, in the fields of atomic absorption spectroscopy (AAS), dialysis, conductivity measurement technology, boron-doped diamond electrodes for the electrochemical degradation of organic substances in process and waste water by oxidation, and the modulation of the speed of sound in ultrasonic transducers. With Schunk at your side, however, you can rely not only on all the above-mentioned product features. We are also happy to put our many years of in-depth market knowledge and our innovative strength at your service.
Our Products for Analytical and Medical Technology
Ultrapure materials for analytics at the highest level
Every day, our products impress with their unique properties in numerous applications in analytical and medical technology. At the same time, our materials impress with their extremely high purity - lowest impurities (ash content) are in the single-digit ppm or ppb range. Rely on our unique product quality, whether graphite components for thermoanalytical processes, for trace analysis or toxicologically harmless materials or products for medical technology - the ultra-pure materials developed by us form the basis, are perfectly matched to the respective application and impress with their reliability and durability.
to your application
We are able to meet the extremely demanding requirements of the market not least thanks to individual options for shaping and surface treatment as well as comprehensive quality management. For example, unique base materials such as isostatically pressed graphite and high-temperature cleaning at up to 2,500 degrees Celsius ensure maximum purity and isotropic material properties. In addition, we can adjust material properties such as density, porosity and sonic velocity specifically to your application. Pyrocarbon coating, which ensures long service life and long-term stable material properties, is also possible, as are resin impregnations for impermeable components, electroplated coatings, or tamped contact for electrical contacting of components.
Products with the best properties
For analytical and medical technology, we can offer high-quality solutions that are toxicologically safe. In addition, our materials are characterized by extremely high long-term stability with regard to their properties such as electrical resistivity and thermal conductivity. They are also robust against chemical attack in acidic and basic environments, have high thermal stability and neither form an oxide layer on the surface nor develop a biofilm on it. Our solutions find a wide range of applications in the fields of AAS, conductivity electrodes, diamond electrodes and ultrasonic transducers, for example.
