The Erlenmeyer Flask Glass Ground Neck is designed for secure mixing, heating, and reaction processes in professional laboratory environments. Manufactured from heat-resistant, durable borosilicate glass in compliance with DIN/ISO standards, it ensures excellent thermal shock resistance, chemical durability, and long service life.

Its thick wall construction, heavy base, and reinforced rim significantly reduce the risk of breakage during washing, handling, and transportation. The perfectly ground NS neck with a smooth interior guarantees excellent leak-proof closure when used with compatible ground glass joints or stoppers, making it ideal for controlled reactions and closed-system applications.

Volume graduations and inscriptions are printed with durable white enamel, providing clear visibility and long-lasting readability even under intensive laboratory use.
