The new DURAN YOUTILITY Bottle System features specially shaped gripping zones on both sides of the bottle to enable easier and safer handling. With the YOUTILITY bottle thread, opening and closing the bottle is significantly faster. The thread is fully compatible with DIN GL 45 closures and other accessories. The slimmer bottle shape allows a more optimal use of limited space in autoclaves and laboratory refrigerators. A pre-defined labelling area is compatible with the dedicated self-adhesive YOUTILITY bottle labels. Nominal volume is shown at the top of the easy-to-read graduation scales for faster determination of volumes. The glass body is molded from borosilicate 33.3 pharmacopoeial Type 1 neutral glass. DURAN glass offers very good chemical resistance and high temperature resistance. Each YOUTILITY bottle is supplied as a complete system, with pouring ring (PP) and a GL 45 cap (PP).
