The biochemical analyzer BS-2800M has a powerful sample examination ability. Thanks to a double sample needle and double reagent needle, it can respond quickly and test at high speed. Moreover, the design of its upper and lower double-layer buffer area makes it possible to flexibly schedule samples, and the test results can be obtained in 10 minutes, thus buying time for critically ill patients. Sample quality monitoring based on serum index detection technology, reagent replacement based on split-screen display, and full-automatic maintenance function make work simpler, saving laboratory manpower.
