The Borosilicate glass tube is an extremely versatile product manufactured from borosilicate glass, which includes boric oxide, silica, and alkali. These tubes display notable resistance to thermal shock due to their low thermal expansion coefficient, making them perfect for applications requiring swift temperature changes. They are also highly resistant to chemical corrosion, which makes them suitable for laboratory use.

Applications
Borosilicate glass tubes are commonly used in scientific laboratories for test tubes and glass piping, in cookware due to their thermal resistance, and in various industrial settings for level gauges, lighting, and more. They’re a crucial component in high-quality products like medical devices, and devices used in space exploration. Our red-line borosilicate sight glass tube, with a red line between two white lines, offers enhanced readability of liquid levels.
