Product Description

Laboratory round bottom flask is a borosilicate glass flask that is used in the laboratory for holding chemicals (reagent flasks) whose bottom is flat and can thus be conveniently placed on the table or in a cabinet.




Superior Thermal and Chemical Resistance

Made from borosilicate glass, the round bottom flask withstands rapid temperature changes and direct flame or heating mantle application. Its uniform wall thickness provides durability and excellent chemical resistance, making it ideal for various laboratory operations that involve exposure to heat and corrosive substances.


Versatile Laboratory Applications

This laboratory flask caters to a wide range of procedures including boiling, chemical reactions, and distillation. Its round bottom design ensures even heat distribution, while available options in neck configuration and capacity allow customization to meet different research and laboratory protocols.

FAQ's of laboratory round flask:


Q: How should the laboratory round bottom flask be cleaned and sterilized?

A: The flask is autoclavable, meaning it can be sterilized in a standard laboratory autoclave. For cleaning, use appropriate laboratory detergents and rinse thoroughly with distilled water. Avoid using abrasive materials that might scratch the glass.

Q: What substances or solvents are safe to use with this flask?

A: The borosilicate glass construction is highly resistant to most chemicals and solvents commonly used in laboratories, including acids, bases, and organic solvents. Always consult chemical compatibility charts for specific reagents before use.

Q: When is it appropriate to use a single, double, or triple neck flask variant?

A: Choose a single neck flask for simple heating or reactions where only one access point is required. Double or triple neck variants are useful for experimental setups that require the simultaneous addition of reagents, insertion of temperature probes, or reflux condenser attachment.

Q: Where is the round bottom flask most commonly used?

A: These flasks are standard equipment in research, educational, and industrial laboratories across India and worldwide, primarily utilized for chemical reactions, distillation, and boiling procedures.

Q: What are the benefits of the round bottom design?

A: The spherical body ensures uniform heat distribution during heating, reducing the risk of localized overheating and making the flask particularly well-suited to reflux and distillation applications.

Q: Can the flask be used under vacuum or pressure?

A: This flask is designed for use at atmospheric pressure and is not suitable for vacuum applications unless specifically indicated in product documentation. Using it under vacuum or excess pressure may result in breakage.

Q: Is it possible to order the flask with custom graduations or capacities?

A: Yes, custom options for graduations and volume capacities are available upon request. Please contact your dealer or supplier to discuss specific customization needs.
