DURAN 211689109 Reagent Narrow Neck Amber 20000 mL

DURAN 211689109 Reagent Bottle Narrow Neck Amber 20000 mL

The DURAN 211689109 is a 20,000 mL amber reagent bottle with a narrow neck, manufactured from DURAN® borosilicate glass 3.3 and compliant with ISO 4796-2 standards. This is one of the largest capacities available in the DURAN reagent bottle series, designed for bulk storage of light-sensitive reagents and solutions.

The amber glass provides reliable light protection up to ~500 nm, preserving the integrity of sensitive chemicals such as silver salts, iodine, and vitamin solutions. Its narrow-neck design minimizes spillage and allows safer handling during pouring, even with large volumes. The heavy-duty borosilicate construction ensures excellent chemical resistance, high thermal performance, and mechanical strength, making it suitable for intensive laboratory and industrial use. The bottle is also autoclavable (~121 °C) for sterilization and repeated use.
