Laboratory Crucible

Laboratory Crucible is a graphite container designed for laboratory-scale high-temperature melting, heating, and material processing applications. 

High-Temperature Stability
Manufactured with thermally stable graphite materials, suitable for vacuum and inert atmosphere environments up to 2200°C.
High-Purity Graphite Material
Produced with high-purity isostatic graphite featuring low impurity levels and stable material properties for laboratory heating processes.
Excellent Chemical Inertness
Graphite's stable chemical structure provides resistance to acids, alkalis, and most molten materials. 

Metal Melting Research
Used for laboratory-scale melting and thermal testing of non-ferrous metals such as gold, silver, copper, and aluminum.
New Material Development
Applied in research projects requiring high-temperature melting, sintering, and thermal treatment of experimental materials.
Chemical Analysis Experiments
Used for high-temperature chemical analysis processes requiring crucibles with low contamination risk.
Powder Metallurgy Research
Used for heating and processing metal powders, ceramic powders, and other experimental materials under controlled conditions.
High-Temperature Material Testing
Used for thermal stability evaluation and high-temperature testing of research materials.
