The Volumetric Flask Glass Amber is designed for precise volumetric analysis and solution preparation in professional laboratories. Manufactured from heat-resistant borosilicate 3.3 glass in compliance with DIN/ISO Class A standards, it delivers reliable accuracy and long-term durability.

The amber glass construction protects light-sensitive reagents from UV exposure, helping maintain chemical stability during preparation and storage. A white meniscus ring mark allows clear and precise volume reading, while white enamel inscriptions provide high visibility and resistance to laboratory conditions.

Each flask is supplied with a leak-proof P.E. stopper, ensuring secure closure, minimizing evaporation, and preventing contamination. This makes the flask suitable for routine analytical work as well as long-term solution storage.
