The solution should be let out of the burette until the indicator changes colour and the value on the burette should be recorded.

The initial and final readings on the burette ( prior to starting the titration and at the end point, respectively ) should be recorded.

After leveling the liquid in the bottle and burette, the remaining volume of gas in the burette indicates the percentage of carbon dioxide absorbed.

The rubber knob are typically soft and sticky due to properties of rubber, so the burettes are not likely to break or slip during the experiment.

The gas is then passed into the caustic potash burette, left to stand for about two minutes and then withdrawn, isolating the remaining gas via the stopcock arrangements.
18.
The base of the gas burette is connected to a levelling bottle to enable readings to be taken at constant pressure and to transfer the gas to and from the absorption media.

This instrumentation usually included a vacuum gauge to indicate intake manifold vacuum, a special odometer to measure distance traveled to hundredths of a mile, and a burette to measure gasoline usage.
20.
Small increments in volume should be added near the equivalence point which is found graphically by noting the burette reading corresponding to the maximum change of emf or pH per unit change of volume.
