Laboratory Bottle Amber Duran

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 with or 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.
