Laboratory Flasks You Will Often Encounter Across Laboratories

There are different kinds of laboratory equipment and tools that you will come across in the current market. These tools have been in existence for quite some time now. In the years that followed after they were invented, they have been improved over and over again. Now, you will find much more reliable tools and instruments used in labs.

When you check out labs, flasks are considered as the most popular instruments inside. If you talk about laboratory flasks, you can find several types of them. They are a type of lab glassware that stores liquid and helps do processes like condensation, precipitation, cooling, heating, and mixing. There are different kinds, sizes, materials, and uses for these laboratory flasks.

No matter what lab you are in, there are flasks that are typically utilized. Some of the most commonly used flasks include Erlenmeyer, retort, Florence, Buchner, volumetric, and Schlenk flasks along with fleakers. You will learn more about these commonly used flasks here.

One of the most common lab flasks is the Erlenmeyer flask that is also called a conical flask. Also called conical flask, the base is conical in shape that extends to a cylindrical neck that is small in size. Having this shape makes it possible for lab personnel to easily use a bung to seal the flask and heat it properly. Besides making the heating process easier, researchers will not have any troubles shaking or stirring the flask with the fear of spilling the liquid inside. You can use these flasks for measuring and holding chemical liquid samples as well as boiling, heating, and mixing them.

Another commonly used lab flask is the sidearm or Buchner flask. Although this flask looks like an Erlenmeyer flask, it has another small tube that stars from the side of its neck going up. At the bottom, you will find that it is shaped like a cone with a short neck where the s mall tube goes out. For this flask, you will see that its material is thick glass. From the tiny sidearm tube, you will find a hose barb. The flask is able to catch a flexible hose through this section. With this design, the Buchner flask can easily create vacuums with the use of a Buchner funnel.

One other lab instrument that you should be aware of is the fleaker, which is a combination of a flask, particularly the Erlenmeyer flask, and beaker. With its cylindrical body, it will go up to e neck that curves inward before it can flare out in a rounded opening. Fleakers have a similar function as Erlenmeyer flask, however, they are mostly for liquids.

And last, you have the Florence or boiling flask that is characterized as having a long and thin neck, a large and round sphere, and a rim opening that is slightly flared. The rounded bottom design ensures that one can heat the solution inside of the flask with the use of Bunsen burner. For rounded Florence flasks to stand upright, they require the right support. No need for support for flat-bottom flask variants.
