When only rough approximations are needed, we use a conical flask.

When we want to measure liquid volumes to an accuracy of within about 1%, we use the graduated cylinders. They are for also used general purpose, but not for sensitive quantitative analysis.

When extreme precise or accurate measurements are needed for dilution or preparation of liquid samples, we use the volumetric flask to contain it.

If we are preparing to perform titration, we will have to use a pipette to transfer very accurate amounts of sample.
