In our experiment, we will use the quartz glass instrument. This instrument is of better quality, is one kind of instrument with high temperature resistance, high hardness, accidentally fell also won't happen fragmentation phenomenon, so a lot of labs will use this glass instrument, quartz vertical distillation device is a kind of advanced experimental equipment, in the distillation is not damaged or the pressure is too large. What are the characteristics of quartz glass instruments? Below by Beijing kailiaa quartz glass instrument factory Xiaobian to introduce you.
　　Relatively stable chemical properties of quartz glass instrument, in use process, the quartz glass will not occur chemical changes and in a sharp rise in temperature does not produce rapid expansion, which for laboratory safety have great promise. Low and stable ultrasonic delay performance, the best UV Vis absorption spectrum and the performance of the visible and near infrared spectroscopy, and has a higher than the mechanical properties of ordinary glass. Therefore it is sophisticated technology of modern space technology, atomic energy industry and national defense equipment, automation system, as well as one of the excellent material for semiconductor, metallurgy, chemical, electric light source, communication, light industry, building materials and other industry indispensable.
　　The material of quartz glass instrument is a kind of natural quartz, can be used for high temperature firing before molding, so the hardness of the quartz glass instrument is relatively high, it is not easy to damage. Melting of products with excellent processing capability, in the high viscosity range can the tubes and rods of the same as the ordinary glass workpiece thermal processing, can also be made of diamond or carbide tools for high speed machining, so as to produce a variety of complex shape of the instrument and special products. The performance of quartz glass is mainly determined by its purity, followed by the process or thermal system.
