DURAN 212273604 Wide Neck Erlenmeyer Flask 250 mL
The DURAN 212273604 is a 250 mL Super Duty Erlenmeyer flask with a wide-neck design, made from borosilicate glass 3.3. It belongs to the DURAN “Super Duty” line, which includes enhancements for increased durability—most notably a reinforced rim that improves mechanical strength and impact resistance compared to standard flasks. This helps reduce the risk of breakage during rough handling or automated cleaning systems.
The wide neck provides easier access for filling, stirring, and cleaning. It features approximate white printed graduations for quick volume estimation (not for precision measurements) and a fired-on white ceramic label field for durable, clear marking of contents that withstands repeated cleaning and autoclave sterilization.
Its dimensions are approximately φ85 mm body diameter × 140 mm height. The neck diameter is about 50 mm, allowing easier manipulation and insertion of reagents or closures.
It is autoclavable and supplied in packs of 10, typical for glassware to reduce handling and breakage risk.

Applications & Notes
Suitable for general laboratory work that involves mixing, heating, or storing ~250 mL of liquid.
The wide neck aids in cleaning, adding reagents, or working with thicker mixes.
Durable construction (Super Duty) is good for labs with frequent usage, rough handling, or automated glassware washing.
Because graduations are approximate, don’t use for analytical work that requires high precision.
Handle with care when full or hot; avoid sudden temperature changes (thermal shock) despite the robustness of the construction.
