Beaker
A beaker is a simple container for stirring, mixing and heating liquids commonly used in many laboratories. Beakers are generally cylindrical in shape, with a flat bottom. Most also have a small spout (or "beak") to aid pouring as shown in the picture. Beakers are available in a wide range of sizes, from one millilitre up to several litres.
Erlenmeyer flask or conical flask
An Erlenmeyer flask or conical flask is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer, who created it in 1860.
Flat bottom flask
Basically a flat bottomed flask is just like any other round bottomed flask but can be placed on a flat surface as the flask can sit upright on its own.
They can be used to mix liquids and carry out different chemical experiments just like their round bottomed counterparts. This may involve observing how different chemicals react to each other or when heated with a flame for example.
It can be used to store liquids in a fridge or other location as there is no risk of them falling over and spilling.
Specimen Jar (Gas jar)
A container used for collecting gas from experiments. It looks like a tube with a broad base and a broad opening.
