Product Description

  

Laboratory graphite crucible is used to analyze chemical samples, it can withstand high temperature, corrosion resistance without affecting the analysis result, so it has been widely used in chemical analysis.


We produce high-quality, high-density graphite crucibles for inert gas fusion combustion analysis using only the highest quality graphite and manufacturing tools.

 

 

Our graphite crucibles have been tested over time to stand up to even the most difficult analysis. From the difficult-to-analyze titanium and zirconium to simpler applications like copper and steel, we always have a graphite crucible to meet your needs and quality control measures. We offer graphite for all major OEMs including LECO®, ELTRA®.

The production process of spectral graphite crucible continues to develop, and the current production process can already achieve very good product quality and meet the needs of various chemical analysis.
 

In addition, our laboratory graphite crucible also has good environmental protection properties, the use of the process will not cause pollution to the environment, is a green environmental protection analytical reagent.

In summary, our graphite crucible is excellent for chemical analysis, its application can not only improve the accuracy of analysis results, but also has good environmental protection properties, and has an important role in promoting the development of modern chemical analysis.
