The invention discloses an automatic sample liquid suction and injection filtering mechanism which comprises a supporting bottom plate, a supporting clamping frame is arranged on the front portion of the upper end face of the supporting bottom plate, and a
reagent bottle containing tool is arranged on the side portion of the upper end face of the supporting clamping frame. When the device is used, the precision reliability is high, meanwhile, the consistency of experimental data is improved by at least 90%, the
batch processing efficiency can be effectively improved,
batch manufacturing can be achieved in batches, the experimental time is greatly saved, meanwhile, automatic operation can be achieved, cross
contamination control can be greatly avoided, full-automatic operation can be achieved, 80% of repeated operation can be reduced, and the working efficiency is improved. The mechanical physical isolation of dangerous liquid enables safety accidents to be close to zero, can promote the overall
automation rate of a laboratory to be improved by 30%-50%, and supports efficient and compliant operation of biological
medicine,
environmental monitoring and new material research and development.
