quartz tube quartz glass tube
Glass made from pure crushed quartz is called quartz glass. It is durable and heat resistant and highly desirable as a glass for laboratory equipment, including beakers, flasks, and crucibles. It is also chemically inactive, which is also useful in laboratory settings. A quartz crucible has another property that makes it suitable for heating materials. It resists expansion and contraction due to changes in temperature.
Quartz glass is naturally clear, more so than regular glass. It can be made opaque, however, with certain additives, and quartz glass of this type is sometimes used for making crucibles. Opaque quartz glass is usually white or off white in color, although other colors are possible. A quartz crucible is typically thick walled and both heavier and stronger than a typical beaker, flask or other glass laboratory equipment and often lacks a rolled rim as is often found on many other types of laboratory glass. A quartz crucible may have a close fitting lid.

Using Notices
1. Do not operate in temperature beyond quartz maximum working temperature for long time.
Otherwise, products will deform crystallization or become softening.
2. Clean the quartz products before high temperature environment operation .
Firstly soak the products in 10% hydrofluoric acid, then wash it with high purity water or alcohol .
Operator should wear thin gloves , direct touch with the quartz glass by hand is inhibited.
3. It is wise to extend the lifespan and thermal resistance of quartz products via continuous use
within high temperature environment. Otherwise, interval use shall shorten products lifespan.
4. Try to avoid touch with alkaline substances (such as water glass, asbestos, potassium and sodium compounds, etc.)
when employing quartz glass products in high temperature, which is made of acid material.
Otherwise product anti- crystalline properties will be greatly reduced.
