![]() ![]() The flask is often used for stirring or heating solutions and is purposefully designed to be useful for those tasks. The Erlenmeyer flask is named for Emil Erlenmeyer (1825–1909), a German organic chemist who designed the flask in 1861. What is the purpose of an Erlenmeyer flask? ![]() Volumetric flasks are used to measure volumes much more precisely than beakers or Erlenmeyer flasks. Use volumetric flasks for precise measurement It is used to make up a solution to a known volume. Why use a volumetric flask instead of a beaker? If the burette is not completely dry by the time you use it, the remaining traces of water on the inside will make your titrant more dilute and thereby change its concentration. When you’re cleaning your glassware, you use water to rinse it off. Why titration flask should not be rinsed? This flask shape is also more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface. Round-bottom flasks are used in distillation by chemists as distilling flasks and receiving flasks for the distillate (see distillation diagram). The Erlenmeyer filter flask also has the advantage of avoiding tipping over. Since the base is wide, there is less danger of the liquid rising to the top and spilling out. Why use an Erlenmeyer flask instead of a beaker?Įrlenmeyer flasks are great for mixing chemicals since they have a wide base and can be swirled around without spillage. They are also used to catch liquids from titrations and filtrates from filtering operations. What is a beaker flask used for?īeakers are useful as a reaction container or to hold liquid or solid samples. The scale on its side allows the amount of solution that’s been allowed to flow out to be read off. Conical flasks are better than beakers for this procedure because they can be easily swirled without risk of the contents spilling. Once the solution is in the pipette, it’s then transferred to a conical flask. Why conical flask is better than a beaker? Beakers are better for stirring and mixing liquids.īeakers have a cylindrical shape, with flat bottoms so that that they can be set onto many different types of surfaces, and they usually have a thick top with a spout to make it easier to pour liquids. Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. What is the difference between a beaker a flask and a graduated cylinder?īoth graduated cylinders and beakers are pieces of laboratory glassware that have a specific function. The beaker shape in general drinkware is similar. The exception to this definition is a slightly conical-sided beaker called a Philips beaker. A beaker is distinguished from a flask by having straight rather than sloping sides. 8 How are flasks used in a chemical reaction?īeakers are available in a wide range of sizes, from one milliliter up to several liters.7 How is a beaker used in the laboratory?.6 What is the purpose of an Erlenmeyer flask?. ![]()
