In the presented work, low cost design of automated bio-chemistry analyzer is suggested. The system is designed in a modular way and consists ofoptical assembly, auto-sample, interfacing hardware and software unit. The same may be used in different variants like semi-automatic bio-chemistry analyzer, fully automatic bio-chemistry analyzer. An automated analyzer is a medical laboratory instrument designed to measure different chemicals and other characteristics in a number of blood samples quickly, with minimal human assistance. Blood samples are placed in a rack of test tubes. This rack is rotated through a stepper motor for positioning of blood sample through the measurement chamber of the analyzer. The purpose of the fully automated bio-chemistry analyzer is intended for the labs where heavy load of blood samples is estimate. The principal of operation of a bio-chemistry analyzer is based on Lamberts and Beers law of photo-chemistry. The transmitted light coming out of a liquid contained in a transparent glass depends upon the concentration (C), thickness (T) and intensity of the incident light
