Laboratory Crucibles are high-temperature resistant vessels used for heating, ashing, melting, and chemical analysis in laboratory and educational environments. This category includes porcelain crucibles, nickel crucibles, Gooch crucibles, and porous clay pots, each designed for specific applications such as gravimetric analysis, filtration, and thermal treatment of samples. Crucibles are commonly supplied with lids to minimise contamination, control evaporation, and support controlled heating conditions during experiments.
Porcelain crucibles are widely used for general laboratory heating due to their good thermal stability and resistance to many chemicals, making them suitable for ashing, ignition, and material testing. Nickel crucibles are used where higher temperature resistance and metal compatibility are required, particularly in analytical and metallurgical applications. Gooch crucibles are designed for filtration and gravimetric analysis, allowing separation of solids using filter media, while porous clay pots are used in electrochemical and separation experiments where controlled permeability is required.
These crucibles are commonly used in chemistry laboratories, research facilities, metallurgy, material science, and education settings where reliable high-temperature performance and chemical resistance are essential. Proper selection depends on temperature range, chemical compatibility, and specific experimental requirements.
For quality and compliance reference, ASTM C149 is a recognised standard covering thermal shock resistance of ceramic materials, relevant for porcelain crucibles used in high-temperature applications. ASTM C373 is also applicable for determining water absorption and porosity of ceramic materials, supporting performance evaluation of porous and filtration-type crucibles. ISO 9001 remains a widely recognised quality management system standard supporting manufacturing consistency and reliability where supplier certification is available. These standards should be referenced only where supported by the manufacturer’s specifications and technical documentation.
For LabChoice Australia customers, Laboratory Crucibles provide dependable solutions for high-temperature laboratory processes, supporting accurate analysis and consistent performance across education, research, and industrial laboratory environments.
