• UV protection USP <660> (Spectral Transmission) and EP (3.2.1) compliant; less than 10% spectral transmission between 290 nm and 450 nm
• External only application of the amber colour and safety coating ensures that internal surfaces have standard DURAN® glass properties
• Easy-to-read scale with graduation marks to estimate the content
• 25 ml bottle has a specially shaped glass edge for improved pouring (additional plastic pouring ring is not required)
• Safe storage and shipping of bulk, high-potency active pharmaceutical ingredients (HPAPIs) powders
• Coating process does not use any volatile organic compounds VOCs or isocyanates

DURAN® GL ISO bottles have become the gold standard of multi-functional laboratory bottles since their introduction in 1972. The protect+ safety coated version of the bottles combines the best of both worlds: virtually inert USP/EP Type I borosilicate glass 3.3 on the inside and a protective safety plastic layer on the outside. The bottles are moulded from high-purity, clear glass or externally ambered clear glass that is then coated with a translucent polyamide PA 12 coating to reduce the hazards of broken glass and liquid splashes in the event of breakage.

A combination of high-performance materials and robust design provides a cost-effective usable life. The bottles feature an easy-to-read graduated volume scale. There is a Retrace Code printed on each bottle for manufacturing lot traceability. The amber DURAN® glass bottle versions ensure that light sensitive contents are protected from the effects of photodegradation. The protection against ultra-violet light meets international USP/EP standards. All the protect+ coated bottles are supplied with push-on protective covers to protect the inside of the bottles from contamination during distribution. Matching screw closures and pouring rings can be ordered separately.

Available in a wide range of nominal bottle capacities from 25 ml to 5 L, and neck sizes GL 25 to GLS 80® wide mouth. This bottle series is not autoclavable.
