Our company can produce precision glass tubes, capillary glass tubes, and optical communication glass tubes. The products include conventional round glass sleeves, ultra-thin-walled glass tubes, ultra-thick-walled glass tubes, square tubes and rectangular tubes, square outer and round inner glass tubes, porous tubes, glass capillaries, and special-shaped matching glass tubes, etc. The products are widely used in many fields such as optical devices, basic electronic information components, chemical instruments, etc.
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.
