The DURAN® YOUTILITY laboratory bottle system features a clear functional design language. Laboratory bottles are widely used in scientific research for activities such as sampling, storage, mixing and sterilisation of liquids. YOUTILITY addresses the critical issues of safe handling and bottle identification through the systematic design of the individual components. The bottles with their ergonomic hand grips are made of a highly resistant pharmaceutical grade glass, and are available in four sequential sizes; 125, 250, 500 and 1000 ml. On each bottle the volume graduations and a traceability code are clearly marked in durable white enamel. The ergonomically-shaped screw closure can be safely and comfortably handled by all users, but especially by those with smaller hands or who are wearing protective laboratory gloves. The thread designs in the closure and on the glass bottle have been optimized for fast opening or closing. The bottle bodies and closure feature dedicated areas for the attachment of self-adhesive identification labels. The innovative Bottle Tags fit around the bottle neck and allows the simple colour personalization of bottles that are used in shared work areas.
