Exceptional High-Temperature Performance
Engineered to withstand extreme heat, these tubes are continuously resistant up to 1200°C and can endure short-term temperatures as high as 1450°C. This makes them ideal for demanding chemical syntheses, material thermal processing, and high-temperature catalytic reactions.
Superior Chemical Inertness & Stability
Crafted from ultra-high purity quartz glass (SiO₂ ≥99.99%), these reaction tubes exhibit outstanding resistance to a wide range of corrosive acids, alkalis, and aggressive chemical environments. This ensures pure reaction conditions and significantly extends the service life of the apparatus.
High Light Transmittance & Photoreactivity
With a light transmittance exceeding 90% across a broad spectrum (including UV), these tubes are perfectly suited for photocatalytic reactions, photochemistry, and any application where efficient light penetration is crucial for activating or observing processes.
Low Thermal Expansion & Excellent Thermal Shock Resistance
Quartz glass has a significantly lower thermal expansion coefficient (1/20th of ordinary glass), providing superior resistance to thermal shock. This minimizes the risk of cracking or breaking when subjected to rapid temperature changes, ensuring safety and reliability during dynamic experiments.
Application Scenario
Material Science and Advanced Ceramics Processing
These tubes are frequently used for the synthesis and heat treatment of advanced materials, including new alloys, ceramics, and semiconductors, where precise temperature control and an inert or high-purity atmosphere are critical. Their high-temperature resistance and chemical stability ensure the integrity of both the sample and the reaction environment.
Photocatalysis and UV-Driven Processes
Given their high light transmittance (especially in the UV spectrum), these quartz reaction tubes are fundamental in photocatalytic research and industrial processes. They allow for efficient transmission of UV light to activate catalysts for environmental remediation (e.g., water purification, air treatment) or specialized chemical syntheses.
High-Temperature Gas Phase Reactions and Deposition
Ideal for experiments or production processes involving gases at elevated temperatures, such as Chemical Vapor Deposition (CVD) in semiconductor manufacturing, or gas-phase reactions for creating new compounds. The tubes’ robust construction ensures safety and integrity under these demanding conditions.
Trace Analysis and High-Purity Chemical Storage/Reactions
Due to the ultra-high purity of the quartz material, these tubes are invaluable for applications in analytical chemistry and pharmaceutical production where even minute contaminations are unacceptable. They are used for preparing high-purity standards, performing trace element analysis, or conducting reactions with sensitive, high-purity reagents.
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.
Yes, we offer comprehensive customization services. Our quartz reaction tubes can be tailored to your precise specifications, including varying lengths, diameters, wall thicknesses, and specialized end configurations (e.g., specific ground joints, flanges, or custom sealed ends). Please provide your blueprints or detailed requirements, and our team will work to provide a precision-engineered solution.
Our tubes are manufactured from ultra-high purity fused silica (SiO₂ ≥99.99%), which is inherently inert and highly resistant to almost all acids, alkalis, and organic solvents. This exceptional chemical stability, combined with a smooth, non-contaminating surface, makes them ideal for reactions involving corrosive substances and critical applications where maintaining material purity is paramount.
The significant advantage lies in quartz’s superior optical transmission properties. Our tubes exhibit over 90% light transmittance across a wide spectrum, including crucial UV wavelengths. This efficiency allows for optimal light penetration and activation in photocatalytic reactions, and ensures accurate data collection in various optical analyses and spectroscopic applications where light interaction with the sample is essential.
