Understanding the Common Types of Laboratory Flasks
No laboratory can function as it should without the use of proper tools and equipment. When laboratories opened, these tools and equipment also existed. Over the years, they have gone through changes and innovations. 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. There are different types of laboratory flasks that you will find in the present market. They are a type of lab glassware that stores liquid and helps do processes like condensation, precipitation, cooling, heating, and mixing. With these laboratory flasks, you will learn that they come in an array of materials, sizes, and uses.
There are flasks that you often find inside labs. 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. For this flask shape, it becomes very easy to seal it with a bung so that you can heat the liquid inside. Aside from ease of heating, researchers can also stir or shake the flask without worrying that the liquid will be spilled. Aside from boiling, heating, and mixing liquid chemicals, you can also measure and hold samples inside.
Another flask that you will come across in labs is the sidearm or Buchner flask. It appears like an Erlenmeyer flask with an extra small tube that extends from 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. For this flask, you will see that its material is thick glass. You will find a hose barb at the small sidearm tube. 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. The body still comes in a cylinder shape that goes up in a neck that curves inward before it flares out in a rounded opening. Despite the fact that the function of fleaker is more or less similar to an Erlenmeyer flask, they are usually intended for dealing with liquids.
Lastly, you have the so-called Florence flask or boiling flask that is a round and big sphere of flaks with a rim opening that is slightly flared and a thin and long neck. 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.
