Laboratory Flasks You Will Often Encounter Across Laboratories
There are different kinds of laboratory equipment and tools that you will come across in the current market. These tools have been in existence for quite some time now. Over the years, they have gone through changes and innovations. 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. 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. 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. This article will explain the basics for these flasks.
When it comes to commonly used lab flasks, the most common will have to be the conical flask or Erlenmeyer flask. As its common name implies, this flask comes with a conical base that extends into a tiny cylindrical neck. Having this shape makes it possible for lab personnel to easily use a bung to seal the flask and heat it properly. 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 commonly used lab flask is the sidearm or Buchner 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. 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. 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. Having a cylindrical body, the tool ends with a neck that goes inward through a curve and flares out through a rounded opening. Despite the fact that the function of fleaker is more or less similar to an Erlenmeyer flask, they are usually intended for dealing with 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. 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.
