In another aspect of the embodiment of the present application, there is further provided a kit 200, including the sealing cover 100 and the case 210 described above; the lower cover 120 of the sealing cover 100 can be clamped at the edge of the box 210, so that the sealing cover 100 is connected with the box 210; the cartridge 210 has a liquid storage chamber 211 therein for storing a sample.
In particular, as shown in fig. 1 and 6. The application also provides a kit 200, the kit 200 comprises the sealing cover 100 and a box body 210, wherein the lower cover 120 of the sealing cover 100 can be clamped at the edge of the box body 210, so that the sealing cover 100 is arranged on the box body 210 to seal and shield the liquid storage cavity 211 in the box body 210. The reservoir 211 is used for storing a sample. The reagent box 200 forms the sealing cover 100 through the hinged upper cover 110 and the hinged lower cover 120, so that good sealing degree of the reagent box 200 can be ensured, and adaptability is improved; meanwhile, the upper cover 110 can be simultaneously unsealed when being opened, so that the unsealing process is more efficient and convenient. The specific structure and beneficial effects of the sealing box are described in detail above, and are not described herein.
The above description is only an example of the present application and is not intended to limit the scope of the present application, and various modifications and variations will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
