ABSTRACT:
The invention discloses a reaction cuvette wash unit comprising a cleaning needle assembly, a straight guide pair, a slide screw pair, a motor, a trigger component associated with a cleaning needle of the cleaning needle assembly in a manner to move with that cleaning needle, and a sensor used to sense the position of the trigger component. When the trigger component moves to a predetermined position, the sensor is triggered and sends a signal to a controller such that the controller controls in a manner to stop the motor. Each of cleaning needle components further comprises a sheath holder and an elastic member. The elastic member is designed to provide an elastic contact while the cleaning needles touch the bottom surface of the reaction cuvette, such that a relatively small force is exerted upon the bottom of the reaction cuvette, thereby effectively protecting the reaction cuvette from damage.
