    High-Temperature Resistance

    Quartz glass has high softening and melting points, allowing U-shaped quartz tubes to withstand prolonged use in high-temperature environments without deformation or damage.

    Corrosion Resistance

    Quartz glass exhibits excellent resistance to a wide range of chemicals, ensuring stability in corrosive environments.

    High Transmittance

    The exceptional light transmission properties of quartz glass make U-shaped quartz tubes ideal for applications requiring observation of internal reactions.

    High Electrothermal Conversion Efficiency

    When used as electric heaters, U-shaped quartz tubes offer high electrothermal conversion efficiency, enabling rapid heating and stable operating temperatures.

    Application Scenario

    未标题 1 21

    Electric Heating

    U-shaped quartz tubes are frequently used in applications requiring high-temperature heating, such as industrial furnaces and ovens. Their efficient electrothermal conversion and stable operating temperatures make them well-suited for these purposes.

    未标题 1 14

    Other Fields

    U-shaped quartz tubes also find applications in healthcare, optoelectronics, and environmental protection, serving as heating elements in medical devices, transparent components in optoelectronic equipment, and more.

    未标题 1 20

    Optical Applications

    Leveraging their high transparency and milky white appearance, they can be utilized as optical components or decorative elements in optical instruments and lighting fixtures.

    Quartz U-shaped tubes are commonly used in laboratory instruments, especially for conducting chemical or biological reactions. They consist of two U-shaped quartz tubes forming an inverted U-structure, providing a large reaction surface area and good mass transfer performance, enhancing reaction efficiency and rate.

    Quartz U-shaped tubes can work continuously at 1200°C and even under 1500°C for short periods.

    The manufacturing process mainly includes material selection and preparation, melting, forming, cooling, cutting and grinding, inspection, and cleaning and packaging.

    Avoid Impacts and Vibrations

    Although U-shaped quartz tubes possess good hardness and strength, it’s important to avoid impacts and vibrations during use to prevent cracking or damage.

    Control Temperature Appropriately

    When operating U-shaped quartz tubes at high temperatures, carefully manage the temperature to prevent exceeding the maximum operating temperature, which can lead to deformation or damage.

    Avoid Contact with Corrosive Substances

    Minimize direct contact between U-shaped quartz tubes and corrosive substances like strong acids and alkalis to prevent corrosion and damage.
