A burette is a volumetric measuring glassware which is used in analytical chemistry for the accurate dispensing of a liquid, especially of one of the reagents in a titration. [4] The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined. [5]
Similarly, a eudiometer uses water to release gas into the eudiometer tube, converting the gas into a visible, measurable amount. A correct measurement of the pressure when performing these experiments is crucial for the calculations involved in the PV=nRT equation, because the pressure could change the density of the gas. [10]
A burette and Erlenmeyer flask (conical flask) being used for an acid–base titration.. Titration (also known as titrimetry [1] and volumetric analysis) is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte (a substance to be analyzed).
Burette: used to measure the amount of acid or alkali used in titration: General laboratory stands, racks, filter paper, reagents, etc. Induction coils: as a source of high voltage electricity Cathode ray oscilloscope ' Recording kymograph: historically, used in human or animal experiments to measure and record data Long extension kymograph
The apparatus consists of an intake valve which feeds into a calibrated water or glycerin jacketed gas burette, this burette is then connected by tubing to two or more absorption pipettes containing chemical solutions that absorb the gases it is being used to measure. The intake and each of the absorption pipettes are valved with stopcocks to ...

They come in a variety of sizes, and are used much like a burette, in that the volume is found by calculating the difference of the liquid level before and after. The last graduation mark is some distance from the tip, to avoid errors in measuring the narrower volume of the nozzle. [ 3 ]
