[0002] There are many testing items for drug testing, including drug quality testing, drug ingredient testing, drug heavy metal testing, drug adverse reaction testing, etc. The purpose of drug testing is to prevent unqualified drugs from entering the market and ensure the safety of drugs. The titration method in drug testing is that the titrant is added to the solution of the drug to be tested by a burette until the standard substance (often called titrant) in the titrant reacts completely with the drug to be tested, and the content of the drug to be tested is calculated according to the stoichiometric relationship.

[0003] For example, the Chinese patent with publication number CN217505777U proposes a titration device for drug testing. The patent realizes automatic stirring of the drug solution in the beaker by lifting and lowering the stirring support beam arranged on the main support column and the auxiliary support column and the stirring drive assembly and the stirring assembly arranged on the stirring support beam. The clamping support beam arranged on the auxiliary support column is located above the stirring support beam and one end of which clamps a dropper or funnel. The dropper or funnel adds reagents to the beaker through the titration channel on the stirring assembly, so that the inspector only needs to add reagents to the beaker during titration without manually stirring the drug solution in the beaker.

[0004] The above scheme still has the following disadvantages: after the reaction between the titration reagent and the analyte is completed, the beaker needs to be released and then taken out, and then replaced with another beaker for titration detection, which has low operation efficiency.
