Extreme High Temperature & Chemical Resistance
Crafted from high-purity fused quartz, these crucibles withstand continuous operating temperatures up to 1200°C and demonstrate superior resistance to strong acids and alkalis, ensuring stability and safety in aggressive chemical environments.
Ultra-High Purity & Non-Contaminating
With a minimum SiO2 purity of 99.99%, these crucibles prevent sample contamination and minimize interactions, guaranteeing accurate and reliable results for sensitive analytical procedures like ashing and trace element analysis.
Excellent Light Transmission & Even Heating
Offering up to 94% light transmission, they are suitable for optical applications. The smooth bottom design ensures even heat distribution, preventing hot spots and promoting uniform sample processing, which is critical for precision melting and reactions.
Customizable for Diverse Applications
Available with full custom specifications, including various sizes, shapes, and lid options (such as those with loop handles), these quartz crucibles can be precisely tailored to meet the specific requirements of unique laboratory setups and industrial processes.
Application Scenario
High-Temperature Ashing and Calcination
Widely used in analytical chemistry and material science for the high-temperature combustion of samples (ashing) to determine inorganic content, or for calcination processes, where the crucible’s 1200°C resistance and inertness prevent reaction with the sample.
Trace Element Analysis Sample Preparation
Employed in environmental, pharmaceutical, and food testing laboratories for the preparation of samples prior to trace element analysis (e.g., ICP-MS, AAS), where the ultra-high purity of the quartz prevents extraneous contamination that could affect results.
Handle with care
Quartz glass products are made from valuable materials and must be handled gently to avoid collisions and falls.
Regular maintenance
The maintenance of quartz tubes must be performed regularly to ensure their long-term stable performance. Regularly check the connections, fixings, and mechanical vibrations of the quartz tubes to prevent abnormalities. The exterior of the quartz tubes is prone to contamination from dust and moisture, so they should be cleaned regularly.
Storage environmen
When storing quartz tubes, care should be taken to avoid exposure to mechanical vibrations, shocks, and excessively high temperatures. They should be kept in a dry, cool, and well-ventilated place, avoiding direct sunlight and high-temperature environments.
Our high-purity fused quartz crucibles are designed for exceptional thermal stability and can safely withstand continuous operating temperatures up to 1200°C, making them suitable for most high-temperature ashing, melting, and calcination processes.
Yes, they exhibit superior resistance to most strong acids and alkalis due to their high-purity fused quartz composition (SiO2 ≥99.99%). This ensures minimal chemical interaction and prevents contamination of your samples, which is crucial for accurate analytical results.
Absolutely. We offer full customization for our quartz crucibles. You can specify unique diameters, heights, wall thicknesses, and even custom lid designs (like those with loop handles or specific sealing mechanisms) to perfectly match your specific laboratory or industrial requirements.
