Wide Mouth Erlenmeyer Flasks
Manufacturer: United Scientific
The Wide Mouth Erlenmeyer Flasks from United Scientific are designed to provide the stability and swirling capabilities of a standard conical flask with the added convenience of an enlarged neck opening. This design is particularly beneficial for applications involving the transfer of dry powders, viscous liquids, or the use of large-diameter pipettes and stirring rods. Manufactured from Borosilicate 3.3 glass, these flasks offer superior resistance to thermal shock and chemical attack. Each unit is finished with a heavy-duty reinforced rim to minimize chipping and features permanent white enamel graduations for easy volume estimation.

Features:
- Easy Filling & Cleaning: The wider neck significantly reduces the risk of spills when adding solids or thick liquids and allows for more thorough cleaning with standard laboratory brushes.
- Versatile Tool Compatibility: Accommodates larger magnetic stir bars, thermometers, and automated sensors that may not fit through a standard narrow-mouth flask.
- Thermal Endurance: Safely transition from heating on a hot plate to cooling on a benchtop (when following standard safety protocols).
- Stable Design: The broad base prevents tipping during vigorous swirling or titration, ensuring sample integrity.
Laboratory Maintenance Tips:
- Stopper Sizing: Because these are "Wide Mouth" flasks, they require larger rubber stoppers than standard Erlenmeyers of the same capacity. Always verify the inner diameter (ID) of the neck before selecting a stopper size.
- Heating Safety: When heating liquids, ensure the flask is no more than 50% full to prevent "bumping" or boil-over, which is more common in vessels with larger surface areas.
- Autoclaving: These flasks are fully autoclavable and dishwasher safe. To prevent "etching" of the glass over time, use specialized laboratory-grade detergents.
