Several guide rail slide units are arranged in uniform intervals on mounting rack as a further improvement of the utility model, in guide rail
Centrifugation pipe fixing device and test tube fixing device is respectively set in the pedestal arranged on left and right sides of the lower section corresponding position of slide unit, convenient for criticizing
Measure sample.
When the starting of automatic liquid separation filter, lifting motor drives lifting platform to rise, and centrifugation tube fixing device is risen to only
When point, step-by-step movement electric appliance starts operation, and the piston handle of syringe is drawn high, and syringe is made to extract the sample liquid in centrifuge tube, sampling
After the completion, lifting motor drives lifting platform to reset, and then guide rail slide unit drives pick-and-place liquid device to move to above test tube fixed frame,
Stepper motor operates again, and the piston handle of syringe is advanced downwardly, and makes the sample liquid injecting tube in syringe, infuses in sample liquid
When entering test tube, sample liquid is filtered by filter, after the completion of injection, guide rail slide unit, which drives, picks and places liquid device reset.
The utility model structure is simple, low manufacture cost can reach while be drawn more by the cooperation of motor and syringe
A sample liquid, and it is filtered the purpose of injection, the working strength of reviewer is reduced, detection efficiency is effectively improved, there is behaviour
Make it is convenient, get sample the features such as rapid.
