Laboratory Flasks You Will Often Encounter Across Laboratories
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. As the years passed, these tools have undergone important developments and changes. Today, you will find that these instruments have become much more reliable and accurate.
One of the most common instruments you can find in labs are the flasks. If you talk about laboratory flasks, you can find several types of them. They are a type of lab glassware that stores liquid and helps do processes like condensation, precipitation, cooling, heating, and mixing. 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.
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. 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. 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. For this flask, you will see that its material is thick glass. From the tiny sidearm tube, you will find a hose barb. This is the section that allows catching of a flexible hose. Through this design on the Buchner flask, it can effective create a vacuum as it works with 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. 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. 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. Through your Bunsen burner, it becomes easier to heat solutions inside this flask because of its rounded bottom design. The right support is essential to rounded Florence flasks so that they can stand upright. Other variants come with flat bottoms, though.
