Problems solved by technology
[0013] The technical problem to be solved by the present invention is to provide a heating device for biological experiments of high school students to overcome the need to add different substances or control the reaction temperature separately in the process of biological experiments. Observation of experimental phenomena; when the liquid bath is heated, the operation is difficult, the utilization rate is low, and the sample is prone to uneven heating, which leads to the problem of increased experimental error

The invention discloses a heating device for biological experiments of senior high school students, and relates to the technical field of biological experimental devices. The heating device comprises a heating device body and a partition device, wherein the heating device body comprises a raw material bin, a heating bin body, an air extractor, a one-way valve, a plurality of annular electric heating plates, a heat-insulation frame, a heat-insulation sealing gasket, a bidirectional valve, a handle and an electromagnetic valve; and the partition device comprises a heat-insulation plate, a heat-insulation sealing ring, a spring, a gland and a raw material trough. The number of spaces and compartments of the heating bin body is changed flexibly by the partition device, heating temperatures in the same heating device are different, different reactants can be placed in the compartments in advance, reaction temperature can also be preset, when an experiment is carried out, operation is simple, and observation of an experimental phenomenon is facilitated; and meanwhile, a beaker or a test tube can be clamped on the gland and is heated by liquid bath, the annular electric heating plates respectively uniformly heat the heating bin body in various depths, and experimental errors caused by uneven heating of samples are reduced.
Description
technical field [0001] The invention relates to the technical field of biological experiment devices, in particular to a heating device for biological experiments of high school students. Background technique [0002] Experiment is one of the basic methods of scientific research. According to the purpose of scientific research, exclude the influence of the outside world as much as possible, highlight the main factors and use some special instruments and equipment to artificially change, control or simulate the research object, so that certain things (or processes) occur or reproduce, so that To understand the process of natural phenomena, natural properties, and natural laws, biological experiments are a common type of experiment. [0003] In the process of biological experiments, it is often necessary to study the reaction difference of the same reaction at different temperatures, or the reaction difference between different substances and the same substance at the same te...
