Measuring Unit

The measuring unit includes the calorimeter block and two non-removable reaction vessels (sample and
reference cells). Access tubes extend downward from inside the buret mounting cavity on the top of the
calorimeter. The access tubes serve as conduits for the filling syringe, titrant delivery, and reference needle.
They also provide for titrant equilibration and as a thermal barrier to the environment outside the
calorimeter.

(TED) are used for temperature control and to detect temperature differences between the sample and
