Ultra-Pure Graphite for Precise and Reproducible Measurements
Reduce effort, cost and risk in analytical and medical technology
Analytical and medical technologies increasingly rely on complex, highly precise methods. Absolute accuracy, reliability and safety are essential – and these are exactly the properties that define our ultra-pure carbon and graphite materials. Leverage our extensive material expertise when unique combinations of graphite substrates and customized functional coatings are required. Whether in thermal analysis or conductivity measurement for medical or industrial use – wherever chemical resistance is essential, impurities influence measurement accuracy, or conventional materials fail at high temperatures, our ultra-pure graphite is the first choice.
Perfect for High-Temperature Applications in Analytics
In thermal analysis, graphite handles the heat
In many areas of analytics, material samples are subjected to extreme heat during thermal analysis – pushing other materials to their limits. In contrast, ultra-pure graphite ensures maximum process reliability, chemical inertness and material purity even at very high temperatures. Use the benefits of our graphite materials in the form of crucibles, insulation felts or graphite heating elements. Another major advantage: ultra-pure graphite can be produced cost-effectively – making our premium quality not only technically, but also economically attractive.
Advantages of ultra-pure graphite compared to other high-temperature materials
- Outstanding thermal and chemical resistance
- Consistent mechanical properties even at high temperatures (unlike metals)
- Excellent thermal shock resistance
- Long-term stability under repeated heating and cooling cycles
- High electrical conductivity
- High thermal conductivity
- Easy to machine
- Ash content (impurities) < 2 ppm

Durable and Reliable in Medical Technology
Ultra-pure graphite – the formula for flawless precision
In analytical and diagnostic systems, errors and contamination can have serious consequences. For example, conductivity measurement in dialysis must always be precise, since both harmful metabolic substances and electrolytes like potassium must be removed from the blood. This process is closely monitored via conductivity sensors – where our ultra-pure graphite electrodes come into play. Because graphite is inherently porous and not ideal in raw form, we impregnate the material with high-performance resins. This maintains key long-term properties such as consistent electrical resistance and stable thermal conductivity. It also prevents surface oxidation and biofilm formation. The component is highly resistant to aggressive chemical cleaning agents and offers a long service life. All of this is implemented under ultra-pure conditions – from materials to handling to packaging.
Ideal for conductivity measurement in industrial applications
From water treatment in wastewater facilities, to process control in the food industry, and leak detection in the chemical and biochemical industries – our resin-impregnated graphite conductivity electrodes are trusted worldwide. In measurement, control, and automation systems, they provide highly accurate and reliable conductivity readings. Unlike conventional metal electrodes, our resin-impregnated graphite does not oxidize and is toxicologically safe – enabling long-term, precise and secure measurements.
