The cuvette sits in a metal tower inside the t2. A spring clip pushes the cuvette into a corner for good thermal contact and reproducible positioning. The cuvette is thoroughly buried in the tower so that its temperature will equilibrate closely to the temperature of the metal, requiring a cuvette lifter for extracting the cuvette. For magnetic stirring the t2 has a magnet under the cuvette which is turned by a belt connected to a pulley on a variable speed DC motor. The Peltier unit is mounted on the side of the cuvette tower. Heat is removed from the Peltier using water flowing through a heat exchanger. Each system comes with a submersible pump that is driven directly by the TC 1 temperature controller.
The pump circulates water from a bucket. For work below the dew point temperature, dry gas may be directed to the windows of the cuvette to minimize condensation that would interfere with the measurement. The t2 is mounted in the spectrometer on a post of the height required to have the optical beam of the instrument pass through the optical ports.
