10.5 Peltier MoDUle
This accessory module is fitted into the instrument casing by following the instructions for the Cell
Accessories.
overview of operation
This temperature controlled sample module uses the electronic peltier heat-transfer effect to maintain
a constant temperature around the sample cuvette, heating or cooling as necessary to maintain
control. A desired sample temperature between 20 and 50°C (or 68 and 122°F) that can be set to
a resolution of 0.1°C (1° F) is available within the Accessory settings on the spectrophotometer.
Additional icons and data will appear in the status bar at all times showing the actual temperature and
the set (target) level. Control is fully automatic and once set is stored within the method, needing no
further entry or adjustment when that method is re-used at a later date.
note: Depending on the insulating/conducting properties of the material used in the
chosen cuvette a varying period of equilibration may be required to bring the actual sample
temperature to that shown on the display.
Warning: Do not cover or obstruct the exhaust air vent on the front of the accessory module,
this will adversely affect the temperature regulation and may damage the peltier element or
control components.
