Exceptional High-Temperature Performance
Crafted from high-purity fused silica, these tubes with flanges can withstand extreme operating temperatures, making them ideal for high-temperature furnace applications, thermal processing, and other environments where conventional materials would fail.
Outstanding Chemical Inertness & Purity
Due to the high purity of quartz glass, these tubes exhibit excellent resistance to most acids and alkalis. This chemical inertness prevents contamination of process materials, which is crucial for semiconductor manufacturing, chemical synthesis, and high-purity applications.
High Optical Transparency & Durability
Quartz offers superior optical clarity across a broad spectral range, enabling visual monitoring or allowing for light-based processes (e.g., UV irradiation). Combined with its inherent durability and resistance to thermal shock, these tubes offer a long service life in demanding conditions.
Superior Sealing & System Integration
The precisely manufactured integrated flange provides a robust and reliable sealing surface, allowing for secure connections to vacuum systems, reactors, and other equipment, ensuring leak-tight operation critical for sensitive processes.
Application Scenario
High-Temperature Furnace & Thermal Processing
Utilized as process tubes, reaction chambers, or observation windows in high-temperature furnaces, annealing ovens, or diffusion furnaces, where the quartz’s extreme heat resistance and the flange’s sealing capability are critical for controlled atmosphere processes.
Vacuum Systems & Sealed Environments
Essential components in vacuum chambers, ultra-high vacuum (UHV) systems, or gas delivery manifolds, where the integrated flange provides a reliable, leak-tight seal for maintaining vacuum integrity or containing specific gases.
Chemical Reactors & Corrosive Environments
Employed as reaction vessels or internal liners in chemical processing equipment that handles corrosive gases or liquids at elevated temperatures, leveraging quartz’s exceptional chemical inertness and the flange for secure integration into larger systems.
Optical & Analytical Instrument Components
Used as light guides, sample chambers, or observation ports in specialized optical and analytical instruments (e.g., spectroscopy, plasma systems), where the high optical transparency of quartz and the precise sealing of the flange are necessary for accurate measurements and system integrity.
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 single end quartz tubes can be fabricated with various flange types, including ground flanges for direct sealing or precision-machined flanges designed to be compatible with common industry standards like ISO-KF, ConFlat (CF), or other custom configurations. This ensures seamless integration into most vacuum systems, furnaces, and analytical equipment requiring standard or specialized connections.
The method of sealing depends on the flange type and application. For ground flanges, a high-vacuum grease or specialized sealant might be used. For standardized flanges (like KF or CF), O-rings (Viton, Kalrez for chemical resistance, or others for high temperature) and clamps are typically used for KF, while copper gaskets are common for CF flanges in UHV applications. Always ensure proper cleaning and torquing for an optimal seal.
