Laboratory Flasks You Will Often Encounter Across Laboratories

In the present market, there are all sorts of tools and equipment used in laboratories. These tools have been in existence for quite some time now. 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.

Flasks are among the most popular instruments that you will often see in labs. In the current market, you have several options of laboratory flasks. 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.

No matter what lab you are in, there are flasks that are typically utilized. Aside from volumetric flasks, you also have Erlenmeyer flasks, Florence flasks, fleakers, Buchner flasks, retort flasks, and Schlenk flasks. You will learn more about these commonly used flasks here.

The conical flask called the Erlenmeyer flask is one of the most common flasks that you will encounter across labs. Also called conical flask, the base is conical in shape that extends to a cylindrical neck that is small in size. 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. You can use these flasks for measuring and holding chemical liquid samples as well as boiling, heating, and mixing them.

Another flask that you will come across in labs is the sidearm or Buchner flask. If you look at this flask, it is, in essence, an Erlenmeyer flask with an extended small tube at the side of the neck. The bottom part is still conical in shape with a short neck where you can find the small tube. The whole flask often comes in a thick glass material. The tiny sidearm tube comes in a hose barb. This is a section that catches a flexible hose. With this design, the Buchner flask can easily create vacuums with the use 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. 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.

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. Through your Bunsen burner, it becomes easier to heat solutions inside this flask because of its rounded bottom design. For rounded Florence flasks to stand upright, they require the right support. No need for support for flat-bottom flask variants.
