Description
The Conical Flask (Erlenmeyer Flask) – Narrow Mouth from Osmosis Scientific is a fundamental laboratory vessel designed for safe and efficient liquid handling. Manufactured from premium Boro 3.3 borosilicate glass, this flask provides excellent resistance to chemical corrosion and thermal shock, making it suitable for demanding laboratory environments including research, quality control, and educational applications.
Its classic conical design allows smooth swirling and mixing without spillage, while the narrow mouth helps minimize evaporation and supports controlled pouring during experiments. The flat base ensures stable placement on laboratory surfaces, improving safety and handling convenience during routine workflows.
White enamel graduations provide clear approximate volume reference, allowing users to perform mixing and preparation tasks efficiently. The robust glass construction supports repeated heating cycles and typical laboratory temperature variations without compromising structural integrity.
Available in a wide range of capacities from 25 ml to 5000 ml, this Erlenmeyer flask supports both small-scale analytical work and larger solution preparation requirements. Whether used for titration, heating, reagent preparation, or general laboratory handling, this narrow mouth conical flask delivers dependable performance, durability, and precision for everyday laboratory use.

Frequently Asked Questions (FAQs)
A narrow-mouth Erlenmeyer (conical) flask from Osmosis Scientific is a borosilicate 3.3 glass vessel with a conical body, flat bottom and narrow neck opening. Manufactured to ISO/DIN 1773 standards, it’s used for mixing, heating, titrations, storage and culturing in labs and industrial settings.
Narrow-mouth Erlenmeyer flasks minimize vapor loss and spillage during heating or shaking, making them ideal for volatile solutions and reactions. Wide-mouth flasks allow easier filling but lose more liquid through evaporation. Osmosis Scientific narrow-mouth flasks balance accessibility with safety.
Yes. Borosilicate 3.3 Erlenmeyer flasks can be heated directly on a Bunsen burner, hot plate or heating mantle up to approximately 200–230 °C. Always heat gradually and use appropriate heat distribution devices (wire gauze, heating mantles) to avoid thermal shock.
Narrow-mouth Erlenmeyer flasks are widely used for titrations, flask fermentation, bacterial culturing, chemical reactions, mixing solutions, and heating liquids. They’re essential in chemistry, microbiology, pharmaceutical and food testing labs.
Our flasks are manufactured from heat-resistant borosilicate 3.3 glass with uniform wall thickness, certified to ISO/DIN 1773 standards. They feature ceramic white graduation scales, beaded rims for durability, and are tested for thermal and chemical resistance.
