Narrow Mouth Erlenmeyer Flasks
Manufacturer: United Scientific
The United Scientific Narrow Mouth Erlenmeyer Flasks are engineered to provide the optimal balance of thermal shock resistance and mechanical durability. Also known as "titration flasks," their iconic conical shape and cylindrical neck allow for vigorous swirling and mixing of contents without the risk of splashing or spilling—making them indispensable for titrations, media preparation, and cell culture. Molded from high-quality Type I borosilicate glass, these flasks are designed to handle rapid temperature changes, allowing for safe transition from a hot plate to a cooling bath. Each flask is finished with a heavy-duty reinforced rim to minimize chipping and extend the lifespan of the glassware in high-use environments.

Lead Times May Vary.
Available in versatile pack sizes for daily bench work or bulk cases for facility-wide outfitting.
Key Functional Benefits:
- Swirl Without Spills: The narrow neck acts as a natural splash guard, allowing for homogenous mixing of reagents during sensitive titrations
- Thermal Endurance: Borosilicate construction permits safe heating and autoclaving; these flasks are designed for everything from boiling solutions to long-term incubation
- Standardized Stopper Fit: Necks are precisely sized to accommodate standard rubber or cork stoppers for secure storage or air-tight filtration setups
- Permanent Markings: Includes a large, matte white marking square and high-contrast enamel graduations that resist chemical wear and repeated washing
Laboratory Management Insights:
- Measurement Note: Erlenmeyer flasks are designed for mixing, heating, and storage. While they feature graduations with a ± 5 accuracy, they are not intended for precise volumetric measurement. For exact volumes, always use a graduated cylinder or volumetric flask.
- Stirring Efficiency: The conical shape is perfectly suited for use with magnetic stir bars, providing an efficient vortex that reaches the corners of the flask.
- Autoclaving: When autoclaving liquids in Erlenmeyer flasks, ensure any stoppers or caps are loosened to prevent pressure buildup and potential breakage.
