The technique uses a set of apparatus with which volumes of solutions can be measured to an accuracy of greater than 0.1 cm3. Three important pieces of apparatus are:

- Burette - Measures accurately the volume of a solution added. Readings can be taken to an accuracy of half a division.
- Pipette - Delivers an accurate volume of a solution. Often this is 25 cm3.
- Volumetric flask - Used to make up an accurate volume of a solution, for example, 250 cm3. This could be a standard solution (of exactly known concentration and known solute).

nice

I have some problem over here...

Name the apparatus used by the laboratory assistant to obtain a very accurate solution?
