1 System Description 
1.1  Overview 
The  BS-120/BS-130/BS-180/BS-190  is  a  fully-automated  and 
computer-controlled  chemistry  analyzer  designed  for  in  vitro  quantitative 
determination  of  clinical  chemistries  in  serum,  plasma,  urine  and  CSF 
(Cerebrospinal  fluid)  samples.  BS-120/BS-130/BS-180/BS-190  Chemistry 
Analyzer  consists  of  the  analyzing  unit  (analyzer),  operation  unit  (personal 
computer), output unit (printer) and consumables. 
1.2  System Components 
BS-120/BS-130/BS-180/BS-190 Chemistry Analyzer realizes the ”two-disk + 
one-probe + one-mixing bar” scheme, which means one reaction disk, one 
sample/reagent disk, one sample probe and one mixing bar. Reaction disk is 
where cuvettes are placed; sample/reagent disk is where sample and reagent 
containers are placed; sample probe is used for dispensing R1/R2/S; mixing 
bar is used for mixing after S or R2 has been added. The photometric system 
adopts filter wheel photometer. The cuvettes are replaced manually after the 
tests are finished.
