Using the Excellence titrators from Mettler Toledo, the parameters pH (or potential) and temperature are continuously monitored and registered throughout the whole controlled dosing procedure
In synthesis laboratories, many different preparation and reaction steps are linked to achieve the most efficient process and highest possible yield.
Many of these tasks involve maintaining constant pH or redox potential values or performing dosing operations under strictly defined conditions, for example: a preset volume of one or more reactants has to be added to a vessel during a given time span.
This results in a complete documentation of the synthesis sequence.
Furthermore, limits can be set for these parameters, with the addition interrupted if these are exceeded.
Dosing can also be carried out continuously in the tandem mode with two dosing units, to speed up the addition of larger volumes of reactant.
Indeed with the T90 titrator two different reactants can be added simultaneously in a parallel controlled dosing.
Another strong feature of the T90 titrator is its ability to perform control tasks.
External instruments can be controlled by means of freely programmable TTL signals or by communication via RS 232 interface.
This opens up the possibility of remotely controlling external heating or cooling apparatus, pumps or similar devices.
Altogether the Excellence titration range provides optimum control and allows safe and secure operation for all pH stat and controlled dosing operations within the synthesis lab.
