SF-8050 use voltage 100-240 VAC. SF-8050 can be used for clinical test and pre-operative screening. Hospitals and medical scientific researchers also can use SF-8050. Which adopts coagulation and immunoturbidimetry, chromogenic method to test the clotting of plasma. The instrument shows that clotting measurement value is the clotting time (in seconds). If the test item is calibrated by calibration plasma, it can also display other related results.
The product is made of sampling probe movable unit, cleaning unit, cuvettes movable unit, heating and cooling unit, test unit, operation-displayed unit, RS232 interface (used for printer and transfer date to Computer).
Technical and experienced staffs and analyzers of high quality and strict quality management are the guarantee of manufacture of SF-8050 and good quality. We guarantee each instrument inspected and tested strictly.
SF-8050 meets China national standard, industry standard, enterprise standard and IEC standard.

1. Coagulation method: adopts double magnetic circuit magnetic bead coagulation method, which is carried out on the basis of the continuous increase of the measured plasma viscosity.
The movement of the bottom of the measuring cup along a curved track detects an increase in plasma viscosity. Independent coils on both sides of the detection cup produce opposite electromagnetic field drives moving magnetic beads movement. When plasma does not undergo a coagulation reaction, the viscosity does not change, and the magnetic beads oscillate with a constant amplitude. When the plasma coagulation reaction occurs. Fibrin is formed, the plasma viscosity increases, and the amplitude of the magnetic beads decays. This amplitude change is calculated by mathematical algorithms to get the solidification time.
2.Chromogenic substrate method: artificially synthesized chromogenic substrate, which contains the active cleavage site of a certain enzyme and color-producing substance, which remains after being activated by the enzyme in the test specimen or the enzyme inhibitor in the reagent interacts with the enzyme in the reagent The enzyme cleaves the chromogenic substrate, the chromogenic substance is dissociated, and the color of the test specimen changes, and the enzyme activity is calculated based on the change in absorbance.
3. Immunoturbidimetric method: The monoclonal antibody of the substance to be tested is coated on the latex particles. When the sample contains the antigen of the substance to be tested, an antigen-antibody reaction occurs. A monoclonal antibody can trigger an agglutination reaction, leading to a corresponding increase in turbidity. Calculate the content of the substance to be tested in the corresponding specimen according to the change in absorbance
