Understanding the Common Types of Laboratory Flasks
There are different kinds of laboratory equipment and tools that you will come across in the current market. When laboratories opened, these tools and equipment also existed. As the years passed, these tools have undergone important developments and changes. Now, you will find much more reliable tools and instruments used in labs.
Flasks are among the most popular instruments that you will often see in labs. If you talk about laboratory flasks, you can find several types of them. They are a kind of lab glassware that deals with liquids as well as facilitate in processing them like heating, mixing, cooling, condensation, and precipitation. With these laboratory flasks, you will learn that they come in an array of materials, sizes, and uses.
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.
The conical flask called the Erlenmeyer flask is one of the most common flasks that you will encounter across labs. As its common name implies, this flask comes with a conical base that extends into a tiny cylindrical neck. For this flask shape, it becomes very easy to seal it with a bung so that you can heat the liquid inside. In addition to heating, researchers will not have to worry about spilling the liquid when they stir or shake the flask. You can use these flasks for measuring and holding chemical liquid samples as well as boiling, heating, and mixing them.
Another flask that you will come across in labs is the sidearm or Buchner flask. If you look at this flask, it is, in essence, an Erlenmeyer flask with an extended small tube at the side of the neck. The bottom part is still conical in shape with a short neck where you can find the small tube. The whole flask often comes in a thick glass material. From the tiny sidearm tube, you will find a hose barb. This is a section that catches a flexible hose. Having this design, the Buchner flask can create vacuums with the help of a Buchner funnel.
Another commonly used laboratory instrument is a combination of flask, specifically the Erlenmeyer flask, and beaker that is called a fleaker. Having a cylindrical body, the tool ends with a neck that goes inward through a curve and flares out through a rounded opening. Although fleakers function most similarly to Erlenmeyer flasks, they are intended 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. With this rounded bottom, you can easily heat solutions found in the flask using your Bunsen burner. For rounded Florence flasks to stand upright, they require the right support. You will find some variants with flat bottoms, however.
