Boiling Flask,flat bottom

Boiling Flask, Flat Bottom: Overview

The Boiling Flask with a flat bottom is a fundamental piece of laboratory glassware designed for heating, boiling, and storing liquids while remaining stable on flat surfaces. Constructed from borosilicate glass, this flask offers reliable performance for routine and demanding laboratory tasks. Its flat base allows it to stand securely on bench tops, hot plates, and heating mantles without the need for additional support rings, making it a practical choice for general-purpose heating applications.

The transparent body permits clear observation of contents throughout reactions and heating procedures, while approximate volume graduations provide a convenient guide for estimating liquid levels. The flask is available in a wide range of capacities to suit different sample volumes and procedures.

Features and Benefits

Borosilicate glass construction provides strong resistance to thermal stress and chemical attack, allowing the flask to be used in heating procedures that involve a broad temperature range. The standard taper neck enables direct connection to laboratory stoppers and condensers, supporting integration into distillation and reflux setups. The flat-bottom design provides inherent stability, which is particularly useful when the flask must remain upright during extended heating or when left to stand during sample preparation and storage.

With capacities spanning from 50 ml to 2000 ml, this flask accommodates everything from small-scale preparations to larger batch processes. The transparent walls and approximate graduations together help monitor volume changes and reaction progress at a glance.

Applications and Related Products

The flat-bottom boiling flask is well suited to heating liquids, boiling solutions, performing distillations, and storing prepared reagents. Its versatility makes it a staple in analytical, educational, and research laboratories. For procedures that require a ground-glass connection for assembling complex apparatus, the Flat-Bottom Flask with Joint offers a compatible alternative with a standardized socket.

When an application calls for even heat distribution or efficient boiling under reduced pressure, many laboratories also rely on round-bottom flasks, which are commonly paired with heating mantles. For titration, mixing, and general handling where a stable, wide base and tapered body are preferred, the Conical flask provides a complementary option within the same glassware family.
