With the increasingly high requirements of the laboratory equipment complexity and efficiency, in vitro diagnostics market continues to grow at breakneck speed. Whether it is designed for immune analysis, clinical chemistry, hematology, molecular diagnosis or infectious diseases and other applications, in vitro diagnostic instruments for original equipment manufacturers (OEMs) and deal makers facing to improve the next generation diagnostic instrument efficiency and reliability of the pressure. In addition, due to the application of in vitro diagnostic equipment is very close to clinical care (the operator is usually not trained); therefore, the design of new equipment should be easy to use, more secure and beneficial to the prevention of errors.
