AI Technical Summary
The mixing and shaking structure of existing fluorescence immunoassay analyzers results in weak collision and shear forces during the mixing process due to the overall rotation of the experimental container, which affects the mixing effect and makes it difficult to achieve rapid dispersion covering a larger liquid surface area.
The stirring rod is driven by a servo motor. Combined with a splash-proof cap and a drive assembly, the cap is fixed and removed by a quick-release component to prevent liquid splashing. The up and down position of the stirring rod is controlled by the drive assembly to expand the mixing range.
It improves mixing efficiency, prevents liquid splashing, increases the efficiency of removing the stirring rod and extracting the mixture, and enhances the mixing range and effect.
