DWK Life Sciences DURAN™ Reagent Bottle, Wide Neck, Amber, USP /EP (3.2.1) Light Transmission

The classical stoppered reagent bottles are moulded from amber DURAN™ borosilicate 3.3 Type 1 glass, and are suitable for the storage of liquid and solid chemicals and reagents. The bottles feature a wide conical ground joint neck and comply with ISO 4796-2. The wider neck is more convenient for handling powders. The glass stopper provides an excellent seal that protects the contents from evaporation, oxidation, and contamination. The bottles have a Retrace Code for manufacturing lot traceability and a marking field in permanent white enamel. The amber glass ensures that light sensitive contents are protected from the effects of photo-degradation. The protection against ultra-violet light meets international USP/EP standards and lasts the lifetime of the bottle.
