2.2.3. Reaction rotor with integrated optical system.
The reactions rotor is thermostated at 37ºC. The optical system, made up of a lighting system and a photometric
system takes the readings directly on the rotor reaction wells. The lighting system has a halogen lamp, a lter drum
for the selection of the wavelength form the appropriate beam of light. The photometric system contains a silicon pho-
todiode and the corresponding electronics to obtain a digital value that is proportionate to the light intensity received.
