Import Borosilicate Glass Tube — Buy in Bulk from Supplier in China

Jinan Tyk United Science Co., Ltd supplies borosilicate glass tube with outer diameters ranging from 5 mm to 50 mm and wall thicknesses between 0.8 mm and 3.0 mm, as stated in the product listing. The material conforms to ISO 3585 and USP Type I standards for chemical resistance and thermal stability, making it suitable for precision applications in laboratory and industrial environments.

The glass composition contains approximately 80% silica and 13% boric oxide, giving it a coefficient of thermal expansion of 3.3 x 10^-6 /K, a typical value for borosilicate glass.
