Borosilicate 3.3 glass tube is also known as borosilicate 3.3 glass tubing, borosilicate 3.3 glass cylinder, heat resistant glass tube.
Borosilicate 3.3 glass tube is widely used for laboratory, lighting, food and many industrial applications, it is of high chemical resistance, high hydrolytic resistance, high thermal shock resistance and high light transmission.
Our borosilicate 3.3 glass tube is available in different shapes, diameters and lengths. The shapes are available in round shape, triangle shape, hexgonal shape, inner profile shape and half-cylinder shape, the diameters range from 3mm to 400mm with different wall thickness and length. We can also manuafcture custom shapes and sizes.
