A conical flask, also known as an Erlenmeyer flask, is a type of laboratory glassware that is used for holding and mixing liquids. It has a conical shape with a flat bottom, a narrow neck, and a wide opening, which allows for easy pouring and mixing of liquids. Conical flasks are commonly used in chemistry experiments for tasks such as titrations, heating liquids, and storing solutions. They are also used in biology and microbiology for culturing bacteria and other microorganisms.

A conical flask, also known as an Erlenmeyer flask, is a type of laboratory glassware used for a wide range of chemical and biological applications. It is primarily used for:
1. Titrations:
- Conical flasks with a narrow neck and a precision scale are used for titrations, where a known amount of a reagent is added to a solution of unknown concentration to determine its exact value.
2. Mixing and Reacting:
- The conical shape of the flask allows for efficient mixing and stirring of liquids, making it suitable for chemical reactions. The spout at the top facilitates easy pouring and prevents spills.
3. Preparation of Solutions:
- Conical flasks are used to prepare solutions by dissolving solids or diluting concentrated liquids. The wide base allows for better distribution of heat when using a hot plate or stir plate.
4. Storage:
- Conical flasks can be used for the storage of liquids, particularly those that are sensitive to light or contain volatile substances. The glass material of the flask provides good chemical resistance.
5. Culturing Microorganisms:
- In microbiology, conical flasks are used for the culturing of microorganisms, especially in liquid media. The shape of the flask allows for good aeration and mixing of the culture.
6. Distillation:
- Conical flasks can be fitted with distillation attachments to perform small-scale distillations. The sloped sides and narrow neck help in the collection of distilled liquids.
7. Filtration:
- With the use of a Büchner funnel and filter paper, conical flasks can be used for vacuum filtration to separate solids from liquids.
8. Washing Precipitates:
- After a chemical reaction, conical flasks are used to wash and filter precipitates, separating them from the reaction mixture.
