Please refer to Fig. 1-Fig. 4, the utility model provides a technical solution:

A comparative experiment box for the disinfection effect of explants for tissue culture, in order to facilitate comparative experiments on explants of the same plant, the inventors set up an experiment box 1 and a placing plate 2 . It includes an experimental box body 1 in the shape of a round box. The inner center of the experimental box body 1 is provided with a circular column 10, in which items such as culture liquid bottles can be placed for easy access at any time. The outer side of the annular column 10 is provided with a plurality of partitions 11 extending to the inner wall of the experimental box 1 in an annular shape at equal intervals, and a culture chamber 12 is formed between each adjacent two partitions 11, so that each culture chamber 12 has an equal space . Inside the culture chamber 12 is placed a placing plate 2 that is adapted to its size, for placing the explants, and facilitating the removal of the whole. The top surface of the placing plate 2 is provided with a plurality of through holes 20, so that the culture liquid in the culture chamber 12 can flood the explants through the through holes 20 and make them in a cultured state. The short side end of the placing plate 2 is vertically provided with a sliding block 21 , a sliding groove 210 is opened on the front side of the sliding block 21 , and a hanging plate 22 is slidably connected to the back of the sliding block 21 . The front side of the bottom end of the hanging plate 22 is provided with a limit block 220 that is clamped with the chute 210, so that the slider 21 can move up and down on the front side of the hanging plate 22, so that the placing plate 2 is separated from the culture medium, so as to clearly observe the outside. Implant development status. The edge of the front end surface of the limiting block 220 is provided with semi-circular platforms 221 protruding to both sides for limiting the sliding block 21 to prevent it from slipping off from the front of the limiting block 220 . The top rear side of the hanging plate 22 is provided with an L-shaped clamping block 222 .

In this embodiment, both the experimental box 1 and the placing plate 2 are made of PP transparent material into an integrally formed structure, which is light in weight, good in toughness and rigid in strength, making it durable.

Further, a convex block 13 is provided on the outer side of the experimental box 1 and near the top of the partition 11, and a groove 130 is formed on the top surface of the convex block 13, and the groove 130 can be placed in the recording culture chamber 12. The sterile condition of the explants is a paper sheet for easy identification of each explant.

Specifically, the center of the bottom surface of the experimental box 1 is provided with a convex column 14 for connecting to the base 15 .

Specifically, the outer side of the convex column 14 is provided with a base 15 in a ring structure. A steel sleeve 16 is tightly inserted into the linear circular hole of the base 15. The steel sleeve 16 is inserted into the convex column 14 and can be rotated. The smooth surface can reduce the frictional force, so that the experimental box 1 can be easily rotated, and the experimenter can sit and observe the development of the explants without physical effort.

In addition, the inner width of the chute 210 is smaller than the outer width of the limit block 220. Since the slider 21 is a plastic product, it has a certain elasticity, and the chute 210 can be supported by the two sides of the limit block 220. A clamping force is thereby generated, allowing the placement plate 2 to be adjusted in position.

What needs to be added is that a dial 211 is provided on the front side of the top end of the slider 21 , which is convenient for fingers to hold and move the placing plate 2 up and down.

When the experimental box for comparing the disinfection effect of explants for tissue culture of the present invention is used, the explants of the same plant are put into the placing plates 2 in several culture chambers 12 with the same culture solution after different disinfection operations are performed. Cultivate on the top, and record the sterilization situation in the paper strip, put the paper strip into the groove 130 on the outside of the corresponding culture chamber 12, so as to facilitate the distinction of the explants, so that by the good development of the explants, the judgment place conforms to the Its sterilization situation; by rotating the experimental box 1, the convex column 14 is rotated in the steel sleeve 16, which is convenient for the experimenter to sit and observe at the same position; by pinching the dial 211 and moving up, the placing plate 2 is separated from the culture medium. , which is convenient for clear viewing, and the explants can be left standing on the placing plate 2 so that the culture fluid flows into the culture chamber 12 through the through holes 20 to avoid waste.
