Detailed size parameters are provided in the options. Please select the appropriate size before purchasing. The displayed sizes are all external dimensions
We offer two options: with a lid and without a lid. Please choose according to your actual usage needs. The lid is a quartz glass plate made of the same material as the main body of the crucible, with four anti-slip points on its surface
The softening point of quartz glass is approximately 1730℃. It can be used for a long time at 1100℃, and the maximum short-term operating temperature can reach 1450℃. Quartz glass has an acid resistance 30 times that of ceramics and 150 times that of stainless steel. Especially in terms of chemical stability at high temperatures, it is unmatched by any other engineering material
Good thermal stability: The coefficient of thermal expansion of quartz glass is extremely small, capable of withstanding drastic temperature changes. Excellent light transmission performance: Quartz glass has good light transmission performance throughout the entire spectral band from ultraviolet to infrared. The visible light transmittance is above 93%, and especially in the ultraviolet spectral region, the maximum transmittance can reach over 80%
Excellent electrical insulation performance: The resistance value of quartz glass far exceeds that of ordinary glass, making it an excellent electrical insulating material. It can maintain good insulation performance even at high temperatures
