Description

Teaching is with cell biological section save set Technical Field The invention relates to the field of biological teaching experiment equipment, in particular to a cell biological slice preservation device for teaching. Background In biological teaching in higher institutions and middle schools, a large number of prepared biological slice specimens are often used for students to observe in turn. These sections are typically supported on slides, the key to their long-term storage being to maintain a low temperature, dry stable environment to inhibit sample degradation, mold growth, and reagent crystallization. At present, a common slice preservation mode in a teaching laboratory mainly comprises the following steps of firstly using a simple glass box or a drawer cabinet, wherein the mode can only provide physical protection, cannot control temperature and humidity, is easy to be affected by environmental fluctuation to deteriorate, secondly placing the slice in a common sealed box with a built-in drying agent, and can improve humidity but cannot control temperature, and when the slice is frequently opened and closed for storage, the whole humidity in the box can be quickly unbalanced, and thirdly, adopting a small electronic semiconductor constant temperature and humidity box, which can provide a better preservation environment, but has the problems of high purchase and maintenance cost, dependence on continuous power supply, serious disturbance of the internal environment when the slice is opened for storage and the like. For teaching scenes requiring frequent, grouped access to a large number of heterogeneous slices, the prior art either fails to provide an effective preservation environment or has irreconcilable contradictions between access convenience and environmental stability. Therefore, a special teaching slice storage device which can ensure that each slice is independently in a stable microenvironment, is convenient to access and manage quickly and does not depend on external power is needed. Disclosure of Invention Aiming at the defects existing in the prior art, the invention aims to provide the cell biological slice preservation device for teaching, which can ensure that all slices are independently in a stable microenvironment and is convenient for quick access and management.
