A conical flask, also known as an Erlenmeyer flask, is a piece of laboratory glassware characterized by its conical shape and flat bottom. This design allows for efficient mixing, swirling, and heating of liquids without significant risk of spillage. The narrow neck of the flask facilitates the secure placement of stoppers or condensers, making it ideal for use in titrations, reactions, and other procedures where control of the contents is essential. Made from heat-resistant borosilicate glass.
