Graduated protect+ plastic safety coated Laboratory Bottles
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 ambered 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 25mL to 5 litres, and neck sizes GL25 to GL45.
