We can make and supply the borosilicate glass tubes with the thermal expansion cofficient 3.3,like Pyrex Corning and Duran Schott;The sizes ranges from O.D3mm upto 315mm,standard length is 1500mm. Products are well-known for their stability and pressure resistance, good workability and high thermal shock resistance. The glass has a very low rate of thermal expansion which makes it an excellent material for laboratory glassware and for use in large-scale technological plants in the chemical apparatus industry. It is resistant to corrosion and remain absolutely neutral, even to aggressive chemicals, in nearly all fields of chemistry. This gives them a great advantage over other materials. Borosilicate glass is extremely resistant to water, acids, salt solutions, organic substances and halogens. Tubing, capillary and rod also have a high alkali resistance for physical and chemical properties. The quality has been approved by the ovresea buyers like South Korea,Japan,USA,Germany etc. Tubes are packed in seaworthy cartons,approx 20kgs per carton;wooden pallets are also available upon request. Good quality at competitive rates are available.
