Experiment is one of the basic methods of scientific research, but also indispensable in biological chemistry class teaching method.How to give play to the role of biochemistry experiment teaching, cultivate students' learning interest and improve the quality of learning, cultivate social service of high quality talents, biochemistry analyzer is based on the principle of the photoelectric colorimetric to measuring instrument for certain chemicals in the body fluids.Due to its fast measurement, high accuracy and consumes small dose, is now at all levels of hospitals, epidemic prevention station, family planning service station is widely used.Cooperate to use can greatly improve the efficiency of the conventional biochemical test and earnings.The biochemical instrument common failures have?Electroencephalogram (eeg) vendors would introduce:


Instrument for six months to replace a peristaltic pump, the user can according to their usage, such as doing project is not much, every day for six months peristaltic pump didn't appear aging, leaking, caking phenomenon, can also be extended use, such as less than six months will appear aging, leaking, caking phenomenon, should be early on.


Monochromator and the detector


Monochromator is one of the core components of the optical system, should notice moistureproof, especially to prevent mildew filter be affected with damp be affected with damp.Except moisture detector, should also be insulated, once be affected with damp be affected with damp dust, can reduce the high impedance amplifier circuit resistance, decreased the detection sensitivity.So that need to be replaced periodically instrument internal desiccant, or take action make the instrument room humidity to maintain the appropriate level.


Instrument piping system
