Flow Cell Base Assembly

3.2.4.1 Introduction
The flow cell, temperature control elements, analogue board and etc are installed and
positioned by the flow cell base assembly. Two modes—flow cell and cuvette are
available on the system. Manual replacement is supported. The temperature control
system is composed of semi-conductor refrigeration plate, air duct, temperature
sensor and insulation material, providing 37℃, 30℃ and 25℃ which are needed on
the system. Analogue board collects the data of absorbance and temperature.
