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. 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. There are different types of laboratory flasks that you will find in the present market. They are a type of lab glassware that stores liquid and helps do processes like condensation, precipitation, cooling, heating, and mixing. These laboratory flasks come in an array of uses, materials, and sizes.
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. This article will explain the basics for these flasks.
The conical flask called the Erlenmeyer flask is one of the most common flasks that you will encounter across labs. With this flask, you will find that it has a small and cylindrical neck as well as a conical base. Having this shape makes it possible for lab personnel to easily use a bung to seal the flask and heat it properly. Aside from ease of heating, researchers can also stir or shake the flask without worrying that the liquid will be spilled. Aside from boiling, heating, and mixing liquid chemicals, you can also measure and hold samples inside.
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. Thick glass is often used to create this flask. You will find a hose barb at the small sidearm tube. This is a section that catches a flexible hose. Having this design, the Buchner flask can create vacuums with the help of 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. With this rounded bottom, you can easily heat solutions found in the flask using your 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.
