Extreme High-Temperature Durability
Designed for long-term use at 1200°C and capable of withstanding short-term temperatures up to 1450°C, these crucibles are ideal for demanding high-temperature processes like ashing, ignition, and material synthesis that would compromise conventional crucibles.
Exceptional Chemical Stability & Purity
Crafted from high-purity fused quartz, they offer superior chemical resistance to a wide range of acids and bases, preventing material degradation and ensuring no contamination of samples, which is crucial for sensitive analytical work.
Superior Thermal Shock Resistance
Due to the extremely low coefficient of thermal expansion of quartz glass, these straight-wall crucibles can endure rapid heating and cooling cycles without cracking or breaking, significantly enhancing safety and operational flexibility.
High UV Transmittance & Optical Clarity
With a UV transmittance rate exceeding 85% in the ultraviolet spectral range and excellent overall transparency, these crucibles are uniquely suited for applications involving UV irradiation, such as photochemical reactions or spectroscopic analysis.
Application Scenario
High-Temperature Ashing, Calcination, and Ignition
Ideal for gravimetric analysis, determining ash content in various materials, or for calcining and igniting precipitates at very high temperatures (up to 1200-1450°C) without risk of crucible degradation or sample contamination.
Strong Acid Digestion & Fusion
Used for the digestion of samples with concentrated acids (excluding hydrofluoric acid) or for high-temperature fusions where the superior chemical inertness of quartz is essential to prevent reaction with the crucible material.
High-Purity Material Synthesis & Annealing
Employed in specialized fields like semiconductor manufacturing, materials science, and ceramics production for synthesizing, annealing, or processing high-purity materials, where preventing contamination and maintaining a stable environment at extreme temperatures is critical.
UV Photochemical Reactions & Spectroscopic Sample Preparation
Due to its excellent transparency to ultraviolet light, these crucibles are perfectly suited for conducting photochemical reactions that require UV irradiation, or for preparing samples that will undergo spectroscopic analysis in the UV range.
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.
You should choose a quartz straight-wall crucible when your application involves extremely high temperatures (up to 1200°C continuously, 1450°C short-term), requires exceptional chemical inertness against most acids and bases, demands high purity with no sample contamination, or needs UV transparency for photochemical reactions. While ceramic and platinum crucibles have their uses, quartz excels in these specific, demanding conditions where others may fail or interfere with the sample.
The lid serves to prevent sample loss during high-temperature processes like ashing, ignition, or calcination, and helps maintain a controlled atmosphere above the sample, minimizing contamination from the furnace environment. The securely welded lifting ring on the lid provides a convenient and safe way to handle and transport the hot crucible, reducing direct contact and improving laboratory safety.
To clean, most residues can be removed by rinsing with deionized water and common laboratory detergents. For stubborn chemical residues, strong acids (excluding hydrofluoric acid and hot phosphoric acid) or bases can be used, followed by thorough rinsing. Always handle with care to avoid physical impact. After cleaning, dry completely before high-temperature use to prevent thermal stress from residual moisture. Proper storage, avoiding scratches to the clear surfaces, will also extend its lifespan.
