A device for realizing gradient temperature control in a petri dish

Abstract

The invention belongs to the field of temperature control of culture dishes, and discloses a device for implementing gradient temperature control on a culture dish. The device comprises a heating module, a heat dissipation module, a measurement module and a control module, wherein the heating module is used for precise and independent heating on a solution in each cell of the culture dish, and heating of different depths and different zones in the culture dish to be heated is realized by adjusting the length and arrangement of thermal conduction needles in the module to form a gradient temperature field in the culture dish to be heated; the heat dissipation module is used for lowering the temperature of the heating module; the measurement module is used for monitoring the temperature in the culture dish to be heated in real time; and the control module is used for adjusting and controlling each module, so that the temperature in the culture dish to be heated reaches a preset temperature threshold. Compared with conventional heating devices, the device achieves more direct and efficient heating on the solution in the culture dish and more precise temperature control.

Description

technical field [0001] The invention belongs to the field of petri dish temperature control, and more specifically relates to a device for realizing gradient temperature control in a petri dish. Background technique [0002] In some biological experiments, it is necessary to discuss the influence of the ambient temperature of cells on their biological activity. At different temperatures, there are obvious differences in the shape of the cells, which are round or oval retracted, and the cytoplasm changes in a beaded shape, or the edges are turned up and fall off in sheets, because the change of temperature causes some organelles of the cells Denaturation, affecting cell growth. By observing the shape of the cells, the cell activity at the corresponding temperature can be inferred, and the cell characteristics can be obtained. Thus, the purpose of screening cells can be achieved by setting the temperature. [0003] Usually, such experiments are carried out in petri dishes o...
