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. When laboratories opened, these tools and equipment also existed. Over the years, they have gone through changes and innovations. Today, you will find that these instruments have become much more reliable and accurate.
Flasks are among the most popular instruments that you will often see in labs. In the current market, you have several options of laboratory flasks. Aside from containing and storing liquids, this kind of lab glassware also helps in performing an array of lab processes like cooling, heating, condensation, precipitation, and mixing. There are different kinds, sizes, materials, and uses for these laboratory flasks.
Inside the lab, you will find commonly used flasks. Aside from volumetric flasks, you also have Erlenmeyer flasks, Florence flasks, fleakers, Buchner flasks, retort flasks, and Schlenk flasks. This article will explain the basics for these flasks.
One of the most common lab flasks is the Erlenmeyer flask that is also called a conical flask. 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. Aside from boiling, heating, and mixing liquid chemicals, you can also measure and hold samples inside.
Another commonly used lab flask 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. At the bottom, you will find that it is shaped like a cone with a short neck where the s mall tube goes out. The whole flask often comes in a thick glass material. You will find a hose barb at the small sidearm tube. This is a section that catches a flexible hose. 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. 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. Through your Bunsen burner, it becomes easier to heat solutions inside this flask because of its rounded bottom design. For rounded Florence flasks to stand upright, they require the right support. You will find some variants with flat bottoms, however.
