2Pcs High Purity Quartz U-Shaped Glass Tubes High-Temperature Resistant High-Transmittance Drying Tubes Chemical Laboratory Equipment (OD/φ10.5mm * H/200mm * ICD/22.5mm)

Size = outside diameter * height * inner clear distance, quantity = 2pcs, U-shaped glass tube SiO₂ purity ≥ 99.99%. The U-shaped quartz glass tube is a glass tube of uniform thickness, with both ends fused and naturally curved to form a semicircular bottom and a vertical upper section. Can withstand prolonged use at 1100°C, with a maximum temperature rating of 1450°C, it exhibits excellent thermal stability, when heated to approximately 1100°C and then placed in room-temperature water, it will not crack. Good electrical conductivity, dielectric constant ≥ 3.7, is an excellent insulating material, can be used for electronic equipment insulation parts, thermal conductivity 1.4W/(m・°C), heat conduction characteristics can be controlled. Mohs hardness level 7, high hardness, anti-wear, coefficient of thermal expansion 5.5×10-⁷cm/cm・°C, thermal expansion and contraction changes are small, in the temperature cycle environment, the structure and size of more stable.
