Understanding the Common Types of Laboratory Flasks

In the present market, there are all sorts of tools and equipment used in laboratories. 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. There are different types of laboratory flasks that you will find in the present market. 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. Some examples include volumetric flasks, Erlenmeyer flasks, Buchner flasks, Florence flasks, Schlenk flasks, retort flasks, as well as 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. With this flask, you will find that it has a small and cylindrical neck as well as a conical base. This shape enables lab personnel to seal the flask using a bung so that they can heat it. 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. 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. Although this flask looks like an Erlenmeyer flask, it has another small tube that stars from the side of its neck going up. Its bottom still comes in conical shape, along with a short neck where a small tube extrudes. The whole flask often comes in a thick glass material. You will find a hose barb at the small sidearm tube. This is the section that allows catching of a flexible hose. With this design, the Buchner flask can easily create vacuums with the use 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. 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. 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.
