The floor-standing BS-2000 Modular System is built as a clinical chemistry analyzer. It can run 2,000 -2,200 tests per hour and offers expandability with different modules. The reversed grating system comes with 13 wavelengths. For ease-of-use, the analyzer features a bi-directional interface (LIS). Reagent and sample probes are offered by a bubble detection feature. An (optional) external air pump helps offer altitude application support of up to 4000m.
