At home in the laboratories of the world for decades.
It was only the invention of DURAN® by Otto Schott that enabled scientists to
push out the frontiers of chemistry and achieve results that had previously been
unattainable. The special composition of DURAN® makes it possible to achieve
maximum possible chemical resistance, minimal thermal expansion, and, thus
resulting, high resistance to thermal shock. This optimum physical and chemical
performance makes DURAN® the obvious choice for use in laboratories.
