DWK Life Sciences™ DURAN™ protect+ Graduated Amber Laboratory Bottle with DIN 168-1 Thread

DURAN™ GL ISO bottles have become ideal 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 molded 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 25 mL to 5 L, and neck sizes GL 25 to GLS 80™ wide mouth.
