In August, SCHOTT AG in Mitterteich set a world record: A DURAN® tube with an outside diameter of 460 mm was produced. This is the largest industrially manufactured glass tube at the moment. The reason for this experiment were customer requests with regard to larger tubes than the usual ones fabricated by SCHOTT, with a maximal outside diameter of 420 mm. Furthermore, tubes with a diameter between 400 and 420 mm and a length of 3 m were produced on request of architecture applications.

Let us know when that tube is ready, Schott.
