Description
DURAN® bottle glass stoppers featuring a hexagonal head and standard ground joint NS 10/19 provide reliable ground-glass closures for laboratory bottles and jointed vessels of corresponding size. The hexagonal profile improves handling when inserting or withdrawing the stopper, while the precision ground taper supports a consistent fit for reagent storage and sample protection. As DURAN® glass stoppers they are intended for routine chemical laboratory use wherever interchangeable NS 10/19 joints are specified. The stoppers help seal bottles against dust and reduce evaporative loss during bench work, storage and transport within the lab. Delivered as a pack of 10 pieces from manufacturer DWK Life Sciences, they are practical for equipping series of bottles or maintaining spare closures of the same joint size. Pack weight is 0,050 kg. Suitable for research, teaching and quality-control environments that standardise on DURAN® bottle accessories and ground-joint glassware systems.
