The invention provides a portable teaching biosafety cabinet. The portable teaching biosafety cabinet comprises a safety cabinet main body and a supporting device, wherein the safety cabinet main bodycomprises a box body and a front cover plate, and can define a sealed internal space; the internal space is divided into a positive pressure room and a clean area; the supporting device comprises a plurality of supporting parts, and can place the portable teaching biosafety cabinet on an installation plane; each supporting part comprises a pivoting part connected with the lower surface of the boxbody and a rod-shaped part for being in contact with the installation plane; each pivoting part is provided with a pivoting shaft basically parallel to the lower surface of the box body; and the rod-shaped parts are connected with the pivoting parts to rotate around the pivoting shafts, and are provided with first positions and second positions which are in a stable state. According to the portable teaching biosafety cabinet, an airflow model of the safety cabinet can be displayed, the sealing failure of the safety cabinet can be demonstrated, the principle of the safety cabinet can be demonstrated, and the filter failure can be demonstrated.
Description
technical field [0001] The invention relates to a biological safety cabinet for teaching and demonstration, in particular to a teaching biological safety cabinet which is easy to carry and move, and belongs to the technical field of biological safety cabinets. Background technique [0002] Biological safety cabinet (Biological Safety Cabinet, BSC) is an infectious microbial experiment during operation or inspection, used to protect personnel, laboratory environment, external natural environment, and experimental samples, and avoid exposure to possible hazards during the above operations. Designed for aerosols and splashes. Infectious aerosols can be generated during handling of liquids or semi-fluids such as shaking, stirring, pouring or dripping a liquid onto a solid surface of a container or another liquid. The reason is that the naked eye cannot see aerosols with a diameter of less than 5 μm, and tiny droplets with a diameter of 5 to 100 μm, so laboratory workers usually...
