Choices! What will it be? #41 FLASK

As I was scrolling through the contest posts put up by @disconnect, I came across this famous post by my friend @patjewell so I couldn't miss out on the opportunity to make my contribution to this contest so here goes...

We will be talking about Flask and in my case it will be about the different laboratory flasks that I use as a Laboratory Technician student. There are so many of these flasks with totally different uses and sometimes related uses. The main thing that's gives them the same definition is that there are used to carry liquids and their differences is in the resistance of the different flasks as I will be listed them out.

Laboratory flasks are vessels with long necks and an open wide body and can be used for mixing, heating, measuring, and holding liquids. The few most used laboratory flasks includes the following along with the main thing they're used for.

• Distillation flasks: These are intended to carry mixtures which are subject to distillation, and can also be used to carry other solutions. They come in different shapes based on the specific experiment but all have just 1 narrow neck, are made of thin glass making it easy to heat, as for shapes, it can either be spherical, pear shaped, test tube shaped, round bottom flask shaped. Examples includes, kjeldahl flasks.

• Reagent flasks: These are the flasks that can be used to hold reagents and keep for future use in laboratory experiments. They can either be flat bottomed so it can be placed conveniently on a table or slab. These flasks are made up of weaker glass contents and so they can't withstand high pressure and temperature environments . They are accompanied by either a ground glass stopper or threaded necks.

• Reaction flask: These are usually round bottomed, they bear multiple necks, 3 to six at most or single necked flasks with ground glass at the end and are, they are made up of very thick glass

To tolerate the high pressure and temperature exerted during reactions, and they are convenient for the mixture of various harmful chemicals like acids as it is very thick. Of these flasks we also have the following which can be used for chemical reactions.
Schlenk flask which is spherical with a long neck and a ground glass ending and a hose outlet alongside a vacuum lock this facilitate the reactions in vacuum and high pressure.

We also have a variety of flasks that I will just list for without explaining but for most of them, the functions is in the name and so no need to over check it...

Round bottom flasks
These are shaped like bulbs with long slender tubes that end at the opening, are used for distillation and heating products.

Cassia flasks
Used for the analysis of oils, aldehyde determination.
Erlenmeyer flask Comes shaped like a cone, with another tube bulging out of it at a joint.
Volumetric flask Shaped like a pear used to prepare solutions of high precision as it is graduated.

The list goes on and on but we should be able to know which flask we need to use to have a the best experimental results because using a wrong flask will impair your work and give false results.

I've come to the end of my presentation today I hope you've been impacted today, please feel free to make arguments and also ask for questions where necessary. I invite @pumpkinbae, and @chant to the contest
