The monitoring, prevention and control of the COVID-19 is inseparable from advanced medical equipment. Among them, the nucleic acid extractor is an important monitoring device for the lysis and purification of viral nucleic acid.

At present, the "New Coronavirus Infection Pneumonia Diagnosis and Treatment Plan (Trial Version 5)" and the US Centers for Disease Control and Prevention and the World Health Organization have determined that real-time fluorescent PCR nucleic acid testing is the basis for confirmation, suspected exclusion, and discharge of new coronary pneumonia cases.
The RNA of the virus is extracted by the nucleic acid detection and extraction instrument, and then the detection kit is used for fluorescence quantitative specific detection. In a short time, it can detect whether the sample contains the nucleic acid of the virus, and finally determine whether it is infected.


The integrated stepping motor is an indispensable key component. The links that NiMotion integrated motor can use in the automatic detection line:
Pick up of test tube, linear motor slide table.
Reagent filling, linear motor sliding table, Z axis optional gravity compensation.
Unscrew/tighten the test tube cover, rotate the motor shaft group, and the controller is equipped with a mechanical function to monitor and limit the torque of the unscrewing/tightening online.
