Volumetric flasks have very distinctive shaped bodies and are for making accurate measurements of specific volumes most often for preparing dilutions.

Beakers

A beaker is a cylindrical shape with a flat bottom and is usually made from glass or plastic. The beakers are employed in mixing as well as in heating and stirring the liquids. Beakers come in a variety of shapes and sizes promoting the accurate measurement of volumes by the scientist. 

Pipettes

Pipettes are very useful devices when accurate measurements of small volumes are necessary. There are various kinds of Pipettes like the volumetric ones, which help in making precision and micropipettes for small amounts. Pipettes are of help in experimental procedures where accuracy in liquid transfer is needed.

Test Tubes

Test tubes are small-sized cylindrical containers made of glass whose function is to contain, combine, or heat small amounts of certain substances. Various sized test tubes are available and they are typically used for qualitative analysis and in experiments. Test tubes are very common in every laboratory and allow for easy and quick reactions and monitoring of the outcome of the reactions.

Burettes

A burette is a long calibrated enclosed glass tube with an aperture at its lower end, which is fixed and is used in dispensing liquid chemicals in specific volumes, more commonly during the titration. They are structured in such a way that controlled amounts of fluids can be expelled which is very crucial in analytical chemistry.

According to Wikipedia, A burette is a graduated glass tube used for titrations that has a tap at one end to dispense known volumes of a liquid. It is a long, graded glass tube with a tapered capillary tube at the stopcock's output and a stopcock at the lower end. The stopcock valve regulates the liquid flow from the tube to the burette tip.

Petri Dishes

Petri dishes are shallow and flat circular dishes used for microbiological study and for the maintenance of solid samples. Constructed from glass or composite polymers they are used to maintain bacterium, fungus, or other specimens in a laboratory. The petri dish is very useful when working in the fields of microbiology and cell cultures.
