Borosilicate Glass Tube

Borosilicate Glass Tube is a tubular form of borosilicate glass. Borosilicate glass has high chemical durability, high thermal shock resistance, low coefficient of thermal expansion and excellent optical properties. Goodfellow offers a range of Borosilicate Glass Tubes in 11 variations. Borosilicate Glass Tubes are used in scientific laboratories and industrial processing due to its resistance to chemical corrosion and ability to withstand rapid temperature changes. They are also used in lighting applications because of borosilicate glass's high light transmission.
