High-Purity Material
Made from high-purity quartz glass, ensuring extremely low impurity content to avoid contamination of sensitive experiments or industrial processes.
Excellent Thermal Resistance
Offers outstanding high-temperature resistance, allowing stable operation in high-temperature environments and making it suitable for applications such as heat treatment or high-temperature reactions.
Chemical Inertness
Quartz glass exhibits excellent chemical inertness to most chemicals, enabling safe use in various chemical environments.
Convenient Flange Connection
Equipped with a standard flange connection, facilitating easy assembly and disassembly with other equipment or piping systems for convenient maintenance and cleaning.
Application Scenario
High-Temperature Reaction Vessels
Due to the high-temperature resistance of quartz glass, they can be used as vessels for high-temperature chemical reactions, such as in pyrolysis or calcination processes.
Semiconductor Manufacturing Equipment
In the semiconductor industry, they can be used as reaction tubes in CVD (Chemical Vapor Deposition) or diffusion furnaces for manufacturing high-quality semiconductor materials.
High-Purity Sample Handling
Can be used as containers for handling high-purity samples, such as in pharmaceuticals and biotechnology, to prevent sample contamination and maintain their purity.
Optical Analysis Instrument Components
Utilizing the good light transmission properties of quartz glass, they can be used as components in optical analysis instruments, such as sample cells or reaction vessels in spectrometers and spectrophotometers.
Typically, this quartz tube can withstand temperatures up to 1200°C, and in some special cases, even up to 1600°C. However, the specific temperature resistance depends on the quality of the quartz glass and the environmental conditions. Please refer to the product specifications for accurate values.
Quartz glass has very good chemical inertness and can withstand most acids, bases, and organic solvents. However, please avoid contact with highly corrosive substances such as hydrofluoric acid (HF), hot concentrated alkalis, and molten alkali metals, which may corrode the quartz glass.
The flange connection, when fitted with appropriate gaskets, provides good gas-tight and liquid-tight sealing. It is crucial to choose a gasket material (such as PTFE, Viton, etc.) that matches the application scenario. Also, ensure that the flanges are properly aligned and the bolts are tightened to the specified torque for optimal sealing.
