Into storage culture dish to be stored.
When specifically used, first place one in each sorting accommodating chamber and pile up culture dish, each culture dish has ware lid and ware
Disk.When needing singly to take out the culture dish in a sorting accommodating chamber, first it is moved upward to support load portion 231 logical
In hole 211, make the upper surface in support load portion 231 about concordant with the upper surface of base plate 210.Culture dish frame 220 is rotated, the sorting is made
Accommodating chamber turns to the top of through hole 211, and the presence due to holding in the palm load portion 231, the culture dish in the sorting accommodating chamber is located at support and carries
In portion 231, will not be fallen by through hole 211.Then, with elevating mechanism 230 support load portion 231 can be made slowly to decline.When the sorting is held
Receive in chamber, bottom culture dish upper surface move to it is concordant with the upper surface of base plate 210 or upper less than base plate 210
During position (preferably concordantly, being slightly above or below) on surface, stop declining, rotate culture dish frame 220, to prevent from holding in the palm
When load portion 231 declines again, it is not necessary to which the culture dish of taking-up also falls.Followed by, continue to decline support load portion 231, make taking-up
Culture dish depart from through hole 211 and culture dish frame 220, carry out follow-up action in order to Ames test instrument.
After many kinds of substance is added in the culture dish for taking out, need the culture dish storage.Specifically, the culture dish is made
In the support load portion 231 of elevating mechanism 230, support load portion 231 carries the culture dish and moves up, when the upper surface of the culture dish
The position for moving to upper surface concordant with the upper surface of base plate 210 or less than base plate 210 (preferably concordantly, is slightly above or omits
Less than) when, stop rising, culture dish frame 220 is rotated, so that a storage accommodating chamber is turned in the upper of through hole 211
Side.Then the lower surface for making the culture dish moves to upper surface concordant with the upper surface of base plate 210 or higher than base plate 210
Position.Culture dish frame 220 is finally rotated, after preventing from asking load portion 231 to decline, the culture dish stored in accommodating chamber falls.So
Culture dish can be made to be stored in storage accommodating chamber.
Further, culture dish frame 220 may include multiple hack levers for vertically extending, upper backup pad frame and lower support
Grillage.Multiple hack levers limit multiple accommodating chambers, for example, limit an accommodating chamber per four hack levers.Lower supporting plate frame and upper
Fagging frame, is respectively arranged in the two ends of each hack lever.Elevating mechanism 230 may also include straight line slide unit, to drive in support load portion 231
Lower movement.Support load portion 231 is preferably bracket or pallet.The lower section of base plate 210 is additionally provided with tumbler, is configured to drive culture
Ware frame 220 is rotated.
Preferably, culture dish storage sorting equipment 200 also includes at least one collet 240, is arranged at each storage and accommodates
The bottom in chamber, each collet 240 is configured to be moved in the presence of the culture dish that support load portion 231 carries is moved up, to allow
The culture dish that support load portion 231 carries is moved upward to its top, and after the culture dish that support load portion 231 carries is moved to above it
Initial position is returned to, to hold in the palm the culture dish for carrying thereon.This kind of setting can make the storing step of culture dish simpler, work as taking-up
Culture dish in be added after many kinds of substance, when needing to store in the culture dish, a storage accommodating chamber is rotated everywhere
In the top of through hole 211, the culture dish is then made in the support load portion 231 of elevating mechanism 230, support load portion 231 carries the training
Foster ware is moved up, until the height in support load portion 231 is higher than collet 240, collet 240 first allows to ask load portion and culture dish to pass through,
After return initial position, then ask load portion 231 to decline, culture dish can be located on collet 240, and this kind of structure can be easy to hold in the palm load portion
