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. When laboratories opened, these tools and equipment also existed. As the years passed, these tools have undergone important developments and changes. In the present, you need not be surprised anymore as to why these instruments and tools are becoming more and more accurate and reliable.
When you check out labs, flasks are considered as the most popular instruments inside. If you talk about laboratory flasks, you can find several types of them. 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. Below are some facts that you can read more about them.
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. In addition to heating, researchers will not have to worry about spilling the liquid when they stir or shake the flask. In addition to mixing, boiling, and heating chemicals, you can utilize these flasks to measure and hold chemical samples in liquid form.
The sidearm or Buchner flask is yet another commonly used lab 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. The tiny sidearm tube comes in a hose barb. The flask is able to catch a flexible hose through this section. Through this design on the Buchner flask, it can effective create a vacuum as it works with a Buchner funnel.
A fleaker is yet another instrument commonly used in the lab that is a hybrid of a flask, in particular the Erlenmeyer flask, and a 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. The rounded bottom design ensures that one can heat the solution inside of the flask with the use of Bunsen burner. The right support is essential to rounded Florence flasks so that they can stand upright. You will find some variants with flat bottoms, however.
