Further, cavity and fixed bracket are made of plastics, and can also be sterilized material capable of washing by any and are made；Cavity It is arranged to transparent or translucent, convenient for observing cell harvestor inside, observation panel or observation window also can be set, Convenient for observation.

The utility model has the advantages that

1, an external air compressor machine or external gas source are only needed, so that it may which completion filters out moisture in sample, to reach receipts Collect the work of cell；

2, on the one hand the air being passed through can drive sample to enter collecting board from sample jar, on the other hand can make humidity Sample drying；

3, sample pot bottom uses cambered design, and all samples can effectively be discharged；

4, sample channel uses similar V-type to design, and avoids sample carryover in pipeline；

5, admission line uses cambered design, keeps air inlet more smoothly；

6, the use of sealing ring, effectively prevent sample to exosmose, and reaches excellent sealing effect；

7, light and handy, it is easy to operate.
