The DURAN® YOUTILITY laboratory bottle system is based on a resistant, high purity technical glass. The shaped glass bottles meet the handling needs of the majority of laboratory staff, especially those with smaller hands. The screw cap is contoured to be easy to use, even when using protective gloves. The key requirement of accurate and easy sample identification is met by the self-adhesive labels for both the bottle and cap. The novel multi-colored bottle tags allow the simple personalization of the bottles in shared work areas. YOUTILITY is available in four sizes; 125, 250, 500 and 1,000 ml each clearly marked in durable white enamel.
