DURAN Original GL laboratory bottles have become the gold standard of multifunctional laboratory bottles since their introduction in 1972. The bottles are moulded from high-purity, amber, USP/EP Type I DURAN® borosilicate glass 3.3, renowned for its excellent thermal performance, and high resistance to chemical attack. A combination of high-performance materials and robust ISO 4796-1 design provides a long working life. The addition of a fused, external amber layer ensures that light sensitive contents are protected from the effects of photodegradation. The protection against ultra-violet light meets international USP/EP standards and lasts the lifetime of the bottle. The amber bottles feature an easy-to-read graduated volume scale, and marking field in permanent white enamel. Permanent Retrace Code on each bottle for manufacturing lot traceability. DURAN Original amber bottles are supplied  without iconic blue polypropylene cap and drip-free pouring ring for use up to 140 °C. All components are fully autoclavable at 121 or 134 °C. The gold standard for multifunctional glass laboratory bottles.
