Laboratory Flasks You Will Often Encounter Across Laboratories
No laboratory can function as it should without the use of proper tools and equipment. These tools have been in existence for quite some time now. Over the years, they have gone through changes and innovations. Today, you will find that these instruments have become much more reliable and accurate.
Flasks are among the most popular instruments that you will often see in labs. 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.
Inside the lab, you will find commonly used flasks. Some examples include volumetric flasks, Erlenmeyer flasks, Buchner flasks, Florence flasks, Schlenk flasks, retort flasks, as well as fleakers. Below are some facts that you can read more about them.
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. 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. 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.
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.
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. You will find some variants with flat bottoms, however.
