Boiling Flask,round bottom

Product Overview

The Boiling Flask, round bottom is a fundamental piece of laboratory glassware designed for heating, boiling, and distillation procedures. Manufactured from borosilicate glass, this flask combines chemical durability with reliable thermal performance, making it suitable for a wide range of routine and specialized applications. Its spherical body allows for even heat distribution across the curved surface, which is why round-bottom designs are preferred when uniform heating is required, such as in reflux setups and distillation trains.

This Round Bottom flask is available across a broad capacity range, allowing laboratories to select the appropriate vessel size for small-scale reactions or larger preparations.

Technical Specifications

• Material: Borosilicate glass
• Capacity: Ranges from 50 ml to 5000 ml
• Neck Size: Standard taper joints available
• Thermal Resistance: Withstands temperatures up to 500°C
• Dimensions: Vary by capacity; typically features a uniform neck diameter
• Weight: Lightweight design for easy handling

Key Features and Applications

Constructed from borosilicate glass, the flask offers strong resistance to thermal shock and chemical attack, characteristics that make it dependable for repeated heating cycles. With a thermal resistance rated up to 500°C, it accommodates demanding procedures involving sustained or elevated temperatures. The availability of standard taper joints means the flask integrates seamlessly with condensers, adapters, and other ground-glass components, supporting the assembly of distillation and reflux apparatus without the need for additional fittings.

The round-bottom geometry is particularly well suited to applications where the flask must rest in a heating mantle or be immersed in an oil or water bath. The curved base maximizes contact with the heat source and promotes consistent boiling. Common uses include:

• Distillation and fractional distillation
• Reflux reactions and synthesis
• Solvent evaporation when paired with appropriate apparatus
• General heating and boiling of liquids

The lightweight design assists with handling and assembly, while the wide capacity range from 50 ml to 5000 ml provides flexibility for scaling procedures up or down. Because the round base is not self-supporting, the flask is typically used with a cork ring, clamp, or stand to keep it stable on the bench.

Related Products

Laboratories that require a self-standing alternative may consider the Boiling Flask,flat bottom, which can rest directly on a flat surface without additional support. For setups that combine bench stability with ground-glass connectivity, the Flat-Bottom Flask with Joint offers a flat base together with a standard taper socket for direct attachment to other glassware. Selecting between round-bottom and flat-bottom configurations generally depends on the heating method and whether the flask must stand independently.
