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, clear, USP/EP Type I 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. 

All components are fully autoclavable at 121 or 134 °C.
