A Quick Guide to Commonly Used Flasks in the Laboratory
In the present market, there are all sorts of tools and equipment used in laboratories. Ever since laboratories came to exist, you will also find these tools. 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. In the current market, you have several options of laboratory flasks. 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. There are different kinds, sizes, materials, and uses for these laboratory flasks.
There are flasks that you often find inside labs. 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.
When it comes to commonly used lab flasks, the most common will have to be the conical flask or Erlenmeyer flask. As its common name implies, this flask comes with a conical base that extends into a tiny cylindrical neck. 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. Aside from boiling, heating, and mixing liquid chemicals, you can also measure and hold samples inside.
The sidearm or Buchner flask is yet another commonly used lab 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. The whole flask often comes in a thick glass material. The tiny sidearm tube comes in a hose barb. The flask is able to catch a flexible hose through this section. Having this design, the Buchner flask can create vacuums with the help 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. 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.
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. Florence flasks with rounded bottoms require proper support for standing upright. No need for support for flat-bottom flask variants.
