Boiling Flask Introduction

Boiling flask is a type of flask used as an item of laboratory glassware . It is used as a container to hold liquids. A Boiling flask has a round body, a long neck, and often a flat bottom. It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use. They are often made of borosilicate glass for heat and chemical resistance.

Uses and methods of flat bottom and round bottom boiling flask

Round bottom boiling flask
Round bottom boiling flask is a kind of flask-like glassware used in the laboratory, used to hold liquid substances, especially suitable for heating and boiling liquids. Round bottom boiling flask are used in higher temperature reactions. This is because the glass thickness of the Round bottom boiling flask is more uniform and can withstand large temperature changes.
It is generally made of heat-resistant glass. The bottom is round, and some of the bottom ends are flattened to make it stand upright. There are one or more necks on it, used to enter and exit the contents, and to connect with other experimental vessels. The neck is slightly trumpet-shaped, and the inner surface is often frosted to closely integrate with other glassware. When in use, fix the bottleneck on the experimental stand with a clamp.
Heating can also be carried out through electric heating pads, water baths and the like. Round bottom boiling flasks are also often connected to a rotary evaporator, and volatile solutions can be removed after heating under reduced pressure.

Flat bottom boiling flask
A flat bottom boiling flask is a kind of flask-like glassware used in the laboratory. It is mainly used to hold liquid substances. Usually, the flat bottom boiling flask is used for the reaction at room temperature and can be slightly heated. It is not necessary to use asbestos net when heating. The bottom is hemispherical, and the upper part has a long neck for easy access. Stand relatively stable on a flat surface.
