The slim shape of the YOUTILITY® bottle saves space when used in autoclaves and laboratory refrigerators. The bottles can also be stored horizontally on their side. A specially marked area fits perfectly with the self-adhesive DURAN® YOUTILITY® labels. The bottles are available in sizes 125, 250, 500 and 1000 ml. They are made from the tried and tested DURAN® borosilicate glass 3.3, a neutral glass that corresponds to glass Type 1 according to the European Pharmacopoeia. DURAN® glass offers very high chemical resistance and high temperature resistance.
