The DWK Life Sciences DURAN® YOUTILITY® GS 45 Amber Laboratory Bottles feature an award winning design.  They are specially shaped with recessed grips on both sides of each bottle ensuring safe and easy handling.  The YOUTILITY’s slim shaped bottles save space when using in lab refrigerators and autoclaves.  Bottles can also conveniently be stored on their sides horizontally.  These bottles are made from DURAN borosilicate glass 3.3, a neutral glass that corresponds to glass Type 1.  DURAN amber glass offers protection against UV light for light sensitive materials.  The color is permanently fired into the exterior glass surface – treatment does not affect the properties of the inner surface of the bottle.
