Quartz Glass Condensing Tube
Quartz Glass condensing tube is a laboratory device used to promote condensation. It usually consists of two quartz glass tubes, one inside and one outside, with the smaller glass tube running through the larger glass tube. It is a glass instrument that uses a heat exchange principle to cool and condense a condensable gas into a liquid. There are three kinds of straight, spherical and serpentine. The specifications are expressed in length (mm) and there are 150~350 kinds. The inner tube of the condensing tube has a mouth at both ends, which can be connected to other equipment of the experimental device to allow the hotter gas or liquid to flow through the inner tube to condense. The outer tube usually has an upper opening on both sides to connect the plastic tube carrying the cooling substance (such as water). When in use, the lower opening of the outer tube is usually connected to the faucet, because the water will automatically flow upward in the condensation tube to achieve a greater cooling effect
