The Volumetric Flask Glass Clear is engineered for accurate volume measurement and reliable solution preparation in laboratory environments. Manufactured from heat-resistant borosilicate 3.3 glass in accordance with DIN/ISO Class A standards, it ensures excellent dimensional stability, chemical resistance, and long service life.

The clear glass body allows full visibility of the contents, making it ideal for routine analytical work and educational use. A blue meniscus ring mark enables precise and easy observation of the liquid level, reducing reading errors. Volume graduations and inscriptions are printed with durable blue enamel, ensuring long-lasting clarity even under frequent laboratory use.

Each flask is supplied with a leak-proof P.E. stopper, providing secure closure to prevent evaporation, contamination, and accidental spillage during storage or handling.
