Complete Specifications
Our Conical Quartz Crucible is manufactured from high-purity quartz glass, specifically 99.99% Silicon Dioxide (4N grade fused quartz).
These crucibles are primarily designed for handling, heating, melting, or igniting substances under high-temperature conditions, suitable for laboratory experiments requiring high-temperature heating, melting, or fusion of various materials, including metals, non-metals, glass, and salts. They are particularly essential for constant weight determination in gravimetric analysis. Due to the outstanding thermal stability and chemical inertness of our high-purity quartz crucibles, their mass remains remarkably stable even after repeated ignition and weighing cycles, ensuring a minimal impact on your experimental results and contributing to the accuracy of quantitative analysis.
Furthermore, the high-purity quartz material is chemically stable, making it the most suitable high-temperature crucible material for analyses requiring high-purity results, such as trace element analysis or the preparation of high-purity materials, as it will not contaminate your samples. High transmittance allows for convenient observation of the sample’s experimental state. High-purity quartz crucibles offer excellent resistance to most acids and alkalis, with the primary exceptions being hydrofluoric acid (HF) and hot phosphoric acid above 300°C.
This conical structure, with its wide opening, narrow base, and inclined side walls, is specifically designed to facilitate decantation and separation during experiments. It helps to concentrate solid precipitates at the bottom, making observation and handling more convenient.
