08 TECHNICAL INFORMATION | PRODUCT SECTION
To colour the products, a special diffusion colour is sprayed solely on the outer surface of the clear glass articles with an innovative spraying method. This technology results in high uniform amber coloring. Afterwards, the coating is burned-in and is therefore resistant to chemicals and cleaning in a dishwasher. The proven DURAN® properties on the inner surface remain unaffected; there is no contact or interaction between contents and amber coating. The uniformity of the amber colouring process ensures the quality of the amber colour which is assured by continuous monitoring.

CONFORMITY WITH STANDARDS AND GUIDELINES
Alongside the international standard DIN ISO 3585, in which the properties of borosilicate glass 3.3 are defined, DURAN® laboratory glassware corresponds to the current standards for glass laboratory apparatus. The relevant DIN/ISO standards are given on the product pages of this catalogue. If the standard is changed, e.g. in case of harmonisation to ISO, our dimensions are adjusted accordingly within an appropriate time interval. DURAN® is a neutral glass of high hydrolytic resistance and thus belongs to glass type 1 in accordance with the European pharmacopeia, the Japanese pharmacopeia and the United States pharmacopeia.
