Quartz tubes are essential components in laboratory tube furnaces, playing a crucial role in various heat treatment processes and material research applications.
Quarts tubes offer excellent thermal stability, chemical resistance, and optical clarity, making them ideal for a wide range of laboratory applications.
Quartz tubes are primarily used as reaction chambers and sample holders in laboratory tube furnaces. When coming with flanges the quarts tube provide a controlled environment for heat treatment processes such as annealing, sintering, calcination, and thermal decomposition. The high purity of quartz ensures that there is minimal contamination of the samples during heating, making them suitable for research in fields such as materials science, chemistry, and metallurgy.
Specifications of Quartz Tubes
Quartz tubes for laboratory tube furnaces are available in various sizes and configurations to suit different furnace designs and applications. From inner diameter of 10mm to 190mm,They are typically made from high-purity fused quartz, which can withstand temperatures up to 1200°C or higher, depending on the grade of quartz used. The tubes are often transparent, allowing for real-time observation of the sample during heating.
Advantages of Quartz Tubes
High Thermal Stability: Quartz tubes can withstand high temperatures without deformation or softening, making them suitable for high-temperature applications in laboratory tube furnaces.
Chemical Resistance: Quartz is highly resistant to chemical attack, making it ideal for use with a wide range of reactive gases and chemicals commonly used in heat treatment processes.
Optical Clarity: Quartz tubes are transparent to visible and ultraviolet light, allowing for easy observation of the sample during heating.
Low Thermal Expansion: Quartz has a low coefficient of thermal expansion, which helps minimize thermal stress and cracking during rapid heating and cooling cycles.
Uniform Heating: Quartz tubes provide uniform heating of the sample due to their excellent thermal conductivity, ensuring consistent results across the entire sample.
Quartz tube for a tube furnace
A quartz tube for a tube furnace is a high-purity cylindrical component made from fused silica (SiO₂), designed to contain samples during high-temperature processes while allowing controlled atmospheres (air, vacuum, or gas flow).
A quartz tube is inserted into a tube furnace and acts as the reaction chamber where heating occurs. It isolates the sample from heating elements while enabling precise control of temperature and atmosphere.
