Quartz tube is an indispensable container in many experiments. It makes our experiments easy and efficient. It is a container that is more important for us. Purity is an important indicator of quartz glass, the physical and chemical properties and the use of a great impact, such as devitrification, high temperature strength, softening point, light conduction, heat chaos, chemical chaos, radiation resistance, fluorescence characteristics, Quartz glass for the semiconductor industry is more demanding on purity.

      Our quartz tube can be used to directly indicate the height of the liquid in the sealed container, with a simple structure, intuitive and reliable, durable, etc., the instrument on the upper and lower valves are equipped with threaded joints, through the flange and the container connected to form a connector, Through the glass plate can be directly read the height of the liquid level inside the container. Instrument in the upper and lower valves are equipped with steel ball, when the glass plate due to accidental damage, the ball in the container under the pressure of blocking the channel, so that the container will automatically seal, can prevent the liquid inside the container to continue outflow.
