Description

An evaporating flask, also known as a rotary evaporator flask or a round-bottom flask, is a type of laboratory flask used in chemical and scientific experiments. It is typically made of borosilicate glass, a type of glass that is resistant to high temperatures and corrosive chemicals.
The evaporating flask is characterized by its round bottom and a wider base, which allows for efficient heating and evaporation of liquids. The flask is attached to a rotating motor, which spins the flask at a constant speed. As the flask rotates, the liquid inside is heated, causing it to evaporate. The evaporated liquid is then collected in a condenser, where it is condensed back into a liquid form and collected for further use or analysis.

Evaporating flasks are commonly used in chemistry, biology, and materials science for a variety of purposes, including the concentration of samples, removal of solvents, and purification of substances. They are available in various sizes to accommodate different volumes of liquid and are typically equipped with a joint that allows for easy connection to a condenser or other glassware components.

It is important to handle evaporating flasks with care, as they can be easily damaged. They should be cleaned regularly to prevent contamination and corrosion, and proper safety procedures should be followed when using a rotary evaporator, as the process can generate heat and high temperatures that pose a risk of injury or fire.
