The Sysmex F-500 is a semi-automated hematology analyzer for in vitro diagnostic use in clinical laboratories. Features and specifications of the Sysmex F-500 include: ·Parameters; WBC, RBC, Hgb, Hct, MCV, ·By changing the analysis mode, WBC and RBC are independently counted. The results of all parameters are immediately printed by the built in thermal printer, ·uL sample size; since only 20uL of whole blood is required, it is possible to analyze samples from neonates or other microsamples with ease and confidence, ·Count time is only 13 seconds per test; WBC and Hgb are simultaneously analyzed. ·From pressing the COUNT key to completing the printout, each analysis cycle requires only 25 seconds, ·The 0.5 ml volumetric sample manometer consistently provides accurate results. A non-mercury volumetric manometer is incorporated into the F-500 to completely eliminates the dangers associated with mercury waste, ·Four programs offer the operator a wide range of flexibility and convenience while insuring a high level of accuracy and precision. These programs include Control Data, Calibrations, Settings, and Tests, ·Automatically performs a recount when an operational error such as noise, clog or HGB AiR Bubble is detected. ·The temperature compensation circuit assures accuracy in counting the conductivity or resistance of diluents change with respect to temperature, as does the voltage amplitude of the detected blood cell signals. This conductivity difference is compensated by a special electronic circuit, ·And easy to operate
