If you work in or are associated with a lab, you probably have a good idea of what the Erlenmeyer flask is. Even if the name does not ring a bell, you will probably understand what we are talking about by the name of conical flask, and recognise it when you see it.
An Erlenmeyer flask in an important lab equipment and piece of glassware that is used to perform a number of different functions. As the name conical flask implies, this flask has a wide base with a flat bottom while the neck is slightly long and narrow.
You may be wondering why this flask has such a confusing name. Well, that is because it was named after the scientist that invented it. Emil Erlenmeyer was a scientist who loved chemistry and gave a gift to the science world in the form of this flask.
This is an important essential in any lab and it is not possible that one does not have it or make use of it during an experiment. But, what exactly are the functions of an Erlenmeyer flask? Scroll below to find out!
The Functions Of An Erlenmeyer Flask
Because of their shape, it becomes easier for them to store liquid and pour from them. They are also used for mixing, cooling, heating and filtering different reagents.
1. Heat And Cool Liquids
Their amazing shape and properties make it very easy to perform all these tasks. They are made from products that are able to withstand extreme temperature changes, hence heating different liquids in them is an easy peasy process.
2. Easily Deal With Corrosive Liquids
Their slanted side and narrow neck also makes it easier to pour liquids without the risk of spillage. Obviously, you need to be careful while pouring any chemical but conical flasks make the lives of lab professionals much easier.
This shape also makes them ideal for corrosive liquids and one that might harm your skin because their shape will not allow them to be spilled or for you to get in contact with them.
3. Mark Them To Get Accurate Results
These funnels are transparent and can also be marked at different levels when you need to pour in specific amounts of reagents. You can easily put signs on them with a red or black marker and carry out your experiments with accuracy.
4. Contain Harmful Contents
Many times, corrosive liquids are needed to put into these flasks which may produce fumes. These fumes are harmful for the body and if inhaled, may cause respiratory and other issues.
With Erlenmeyer flasks, there is the option of containing these liquids in the flask with a cork or stopper so they do not cause any problems or even spill over.
5. Prepare Different Microbes
A very good feature of Erlenmeyer flasks is that they can be used to prepare different kinds of microbes for experimental purposes.
For them to be able to carry out this function, they may be properly sterilised and closed off properly to allow the microbes to grow and allow optimal gas exchange.
How To Use An Erlenmeyer Flask
This is not a very difficult process, but one tends to make mistakes sometimes which is completely normal. Here is a short guide on how to use this flask in a proper manner
● Add The Solute
The first step is to add solute to the flask. This is a fairly easy step but make sure you measure and pour the correct volume. Because if you don't, you might mess up the entire experiment.
● Add The Solvent
Next, add the solvent to the solute. Add just enough so the solute is completely dissolved. Do not pour too much as that might disrupt the calculations and cause the results to be inaccurate. Make sure you start pouring slowly and see the solute dissolving until it completely does.
Stop adding the solvent when it is on the mark defining the end point. The end point can be determined through the marking and the meniscus of the liquid.
● Mix The Solution
Now that the solution has approached the end point, seal the flask with a stopper or cork. Now, shake the solution thoroughly to ensure that it has completely mixed for the best results.
