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.

One of the most common instruments you can find in labs are the flasks. There are different types of laboratory flasks that you will find in the present market. 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. These laboratory flasks come in an array of uses, materials, and sizes.

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.

When it comes to commonly used lab flasks, the most common will have to be the conical flask or Erlenmeyer flask. 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. 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.

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. Its bottom still comes in conical shape, along with a short neck where a small tube extrudes. Thick glass is often used to create this flask. From the tiny sidearm tube, you will find a hose barb. This is the section that allows catching of a flexible hose. With this design, the Buchner flask can easily create vacuums with the use of a Buchner funnel.

Another commonly used laboratory instrument is a combination of flask, specifically the Erlenmeyer flask, and beaker that is called a fleaker. 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. 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. Other variants come with flat bottoms, though.
