“Chemistry Glassware Names and Uses.” ThoughtCo, Feb. The key difference between beaker and Erlenmeyer flask is that beaker is a cylindrical container whereas Erlenmeyer flask is a conical container. Summary – Beaker vs Erlenmeyer Flaskīaker and Erlenmeyer flask are two different laboratory equipment. However, we can cover it with a watch glass or using another large beaker.īelow infographic tabulates the differences between beaker and Erlenmeyer flask. We can easily cover the mouth of the Erlenmeyer flask because it has a narrow neck but covering a beaker is comparatively difficult due to the presence of a spout and its wide mouth. What is the Difference Between Beaker and Erlenmeyer Flask?īaker and Erlenmeyer flask are two different laboratory equipment. Moreover, the narrow neck of this flask allows a funnel to be placed on top of it. During the boiling, the hot vapour condenses on the upper section of the flask, which helps to reduce the solvent loss. Moreover, this flask is suitable for boiling liquids. 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. 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. Both were small, so they are fairly accurate. But in general use, we can cover the beaker with a watch glass. The graduated cylinder and beaker were similar in percent error (2.2 and 3.5 respectively). 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. We can easily distinguish beakers from conical flasks because beakers have straight sides rather than sloping sides. There is a wide range of sizes of beakers, ranging from one millilitre to several litres.

Most beakers have a small spout or a “beak” that is important in pouring liquids. Side by Side Comparison – Beaker vs Erlenmeyer Flask in Tabular Formīeaker is a piece of laboratory equipment having a cylindrical shape and a flat bottom. What is the Difference Between Beaker and Erlenmeyer Flask?Ĥ.

Sucking air from the pipet using a rubber bulb (like a turkey baster) draws liquid up through the tip into the pipet, and a precisely measured volume can then be transferred to another container. Pipets are long narrow glass tubes with a bulb in the center, a hash mark to indicate when they are full, and a narrow tip. Burets are long, tall cylinders-generally much narrower and taller than graduated cylinders-with hash marks to measure volume and a stopcock at the bottom the stopcock can be turned to allow the contents to drip out. Volumetric flasks have a flat-bottomed bulb and a long, narrow neck with a hash mark along the side to indicate the point at which the flask is full. Graduated cylinders are tall cylinders with a spout to pour liquids they have hash marks on the side to measure the volume of their contents. Erlenmeyer flasks have a narrow neck over a conical base, while beakers are basically large open-mouthed glass jars with a lip and spout for pouring.
