Jena graphite tubeIt is a high-quality graphite tube widely used in chemical analysis, laboratory research, and industrial production. The "Jena" in its name refers to the Jena region of Germany, where graphite tubes produced have high quality and performance, making this name gradually synonymous with this type of product.
Characteristics of Jena graphite tube
1. Excellent thermal and electrical conductivity: Graphite itself has high thermal and electrical conductivity, making Jena graphite tubes very effective in experiments that require high temperature and rapid response.
2. High temperature resistance: Jena graphite tubes can withstand high temperature environments, typically up to a temperature range of 1000 ℃ or higher in chemical analysis and experiments. It can maintain stable physical properties even under harsh high temperatures.
3. Chemical stability: Graphite has good chemical stability and can resist acid and alkali corrosion. Therefore, in some special chemical experiments, Jena graphite tubes can ensure that the reaction will not be disturbed by other chemical substances.
4. Low thermal expansion coefficient: The thermal expansion coefficient of graphite tubes is relatively low, so they can maintain dimensional stability in environments with large temperature changes, avoiding unstable factors caused by thermal expansion.
5. Excellent mechanical strength: Although graphite is a soft material, in Jena graphite tubes, after special processing, its mechanical strength is high enough to meet the needs of most industrial applications.
6. Pollution free: The surface of graphite tubes is smooth and not easily reacted with other substances, so in some high-precision analyses, it can avoid the influence of external pollution on experimental results.
