The slanted sides and the narrow neck of Erlenmeyer flask is important in mixing and swirling things inside the flask without any considerable spoilage. We can also easily cover the flask mouth using a ground glass or some other connector.īuchner flask is a derivation of the Erlenmeyer flask which is important in vacuum filtration. Sometimes, the mouth of the Erlenmeyer flask has a beaded lip, which is important in stopping or covering. Also, there can be a wide range of volumes in these flasks. We can produce these flasks depending on the application, e.g. Erlenmeyer flasks differ from beakers in their tapered body and the narrow neck. The shape of an Erlenmeyer flask varies in its base as well as in its sidewalls. This flask was named after the scientist Emil Erlenmeyer after its creation in 1860.įigure 02: Different Sizes of Erlenmeyer flasks Erlenmeyer flask contains the analyte of the titration. In titrations, the flask is placed under the burette. It is a type of titration flask that is important in performing titrations. What is Erlenmeyer Flask?Įrlenmeyer flask is a laboratory flask that has a conical shape and a flat bottom. Alternatively, we can cover a beaker with a large beaker as well. ![]() That is to prevent contaminations and to avoid the loss of components inside. But in general use, we can cover the beaker with a watch glass. Moreover, beaker C has comparatively a small height, and it is named as a crystallizer.ĭue to the presence of a spout, a beaker cannot have a lid. Beaker B has a height that is twice the diameter. ![]() In the above image, the beaker A typically has a height that is about 1.4 times the diameter. But, there are some beakers made of metal such as stainless steel and aluminium. Figure 01: Different Sizes and Shapes of Beakers
