Conical flasks are used for heating, storing, mixing, and performing chemical reactions.However, the beaker’s top spout makes it simple to pour chemicals. The conical flask’s rounded and thin mouth makes pouring easier.On the other hand, beakers lack a cover, making them inappropriate for storing chemicals. Conical flasks with ground glass stoppers are available air tightening makes it easier to store gaseous and other chemicals.Because of the conical flask’s shape, it is better for mixing without spillage than beakers.In contrast, beakers have flat bottoms, straight side walls, and a spout at the top. Conical flasks have a broad base and narrow neck.However, both of them vary in features and applications Differences between Conical Flasks and BeakersĬonical flasks and beakers are made of glass and essential laboratory equipment. The conical flask should be handled carefully when in operation.A conical flask should be stored in a box in a dry location to prevent contamination.After completing the experiment, the flask should be rinsed for 10 to 15 minutes with a warm detergent solution.Before using the conical flask, it should be sterilized and wiped clean.PrecautionsĬautions while handling, or using a conical flask are as follows It can be easily cracked or damaged by improper handling.It has a limited thickness, due to which it cannot be used for high chemical reactions.It is not used for measurement purposes because of its irregular shape. Disadvantages of Conical FlaskĬonical flasks do have some drawbacks despite their benefits, such as The small neck of the conical flask reduces evaporation loss during heating.Its design of having a broad base with a narrow neck helps in stirring or rotating liquid without spillage.The flaring neck of the conical flask helps to pour liquid easily.Therefore, it is used to heat chemicals or reagents. Conical flasks are usually heat resistant in nature.The conical flasks can be used for various purposes like mixing, heating, and storing chemicals or reagents.Advantages of Conical FlaskĬonical flasks are an important laboratory glassware that has the following advantages In microbiology: In the microbiology laboratory, conical flasks are also used to boil and sterilize culture media while preparing the culture plates.In biology: In biology, conical flasks are used to produce microbial culture needed during tissue culture or DNA extraction.The narrow neck and reducing solvent loss can also enhance the capability of recrystallization. The top of the Erlenmeyer flask helps to condense the solvent. Similarly, conical flasks are also used to boil liquids. As a result, it is used in titration experiments. Because of its irregular shape, it is best for swirling liquid. In chemistry: Erlenmeyer flasks are used for various purposes in a chemistry laboratory.Applications of the Conical FlaskĬonical flask has a wide range of applications in the chemistry, biology, and microbiology fields for heating, mixing, and transferring chemicals or reagents The conical flask is built based on ASTM (American Society for Testing and Materials) and ISO specifications (International Organization for Standardization). Similarly, the wide mouth of the conical flask also facilitates the addition of solid samples Available sizes of Conical Flask Wide mouth: Liquid inside it can be stirred by a rod.Narrow mouth: Because of its tiny mouth, it helps to support the funnel during the experiment.Types of Conical FlasksĬonical flasks are available in two varieties based on the width of the mouth Ground glass stopper: Many conical flasks are available with a ground glass stopper that provides an airtight seal so that even gaseous compounds can be stored.High transparency: Conical flasks have a high degree of transparency because they are made of borosilicate glass.Variety of size: Conical flask is available in various sizes that allow a wide range of applications.Heat resistant: It is mainly made of borosilicate glass which makes it heat tolerant.Wide round neck opening: It allows smooth liquid pouring as well as easy cleaning.Precise graduation: It consists of clear and visible graduation in the neck region.Shape: Conical flask has a smooth cylindrical shape with a narrow neck and broad base.
