15.4 Peltier tempered 6- and 8-cell changers
The Peltier-tempered cell changers are automatic sample changing systems.
The temperature control of the cell changers is carried out via a separate
control unit. The rear of the Peltier elements is kept at a temperature near the
ambient temperature by the water cycle of the heat exchanger.
As control sensor a sensor in the top area of the cell block is used. In addition to
the control sensor the cell changer features two further sensors for the optional
registration of the holder or cell temperature.
The cell sensor is designed specifically for standard cells with round plugs from
PTFE and can remain in the cell during the optical measurement.
The cell changers have space for 6 or 8 cells with a path length of 10 mm and
external dimensions of 12,, (L x W x H in mm).5 x 125 x 45
Optionally the cell changers can be equipped with a magnetic stirrer at factory.
The stirring speed is set at the temperature control unit.
Note!
The 6- and 8-cell changers differ by the cell block used and thus the possible
number of cells to be inserted. However, their operation and installation are
identical. Therefore, the two cell changers are described jointly below. For the
illustrations the 8-cell changer has been used. The 6-cell changer is installed
analog in the sample chamber.
