The titrator accessory is designed to accept standard 1 cm x 1 cm cells, and includes a micro magnetic stirrer. The titrator is fully automated from Bio-Kine software with user-defined concentration steps. Automatic increment functions are also available, including a variable function to change the increment during titration.

When acquisition is made using a Bio-Logic spectrometer , a series of titration sequences is done automatically. External detection devices can be synchronized by adjusting the steps and acquisition duration.

The user selects between single wavelength titration and spectral titrations. This permits the addition of the titrant to be stopped once the reaction is complete. The titration procedure is applicable to many different kinds of reactions.
We will however focus our attention on acid-base titrations in which the reaction is neutralization. When an acid-base neutralization is performed the analyst adds a drop or two of an acid-base indicator solution to the solution in the receiving flask prior to the start of the titration.

An acid-base indicator is a chemical dye that is capable of being one colour at a low pH and a different colour at a higher pH. Two common types are litmus, which is red in acidic solutions and blue in basic solutions and phenolphthalein which is colourless in acids and pinkish-violet in basic solutions. In performing the titration, the analyst looks for a change in colour that signals that the solution has changed from acidic to basic or basic to acidic, depending upon the nature of the reactants in the burette and flask.
Usually this colour change is very abrupt as the end of the reaction is approached, the change in colour normally takes place with the addition of only one drop of the titrant.

Then the colour change finally occurs, delivery of the titrant is stopped -- the end point has been reached -- and the total volume of the titrant that was added to the receiving flask is recorded.
