Through the coordinated use of the liquid separator 301 arranged at the bottom of the liquid adjustment container 201, the liquid separator 301 can be a DW-9 series microbial reagent liquid separation device, which is an existing mature technology and will not be introduced in detail here. The liquid is shunted to the liquid separation tube 307 arranged at the through port of the liquid separation connection socket 304 through the connecting tube 303 arranged at the bottom of the liquid separator 301, and finally the micro liquid is dispensed into the test tube through the liquid separation tube 307.
