Description

Technical Field

[0001] The utility model relates to the technical field of soil organic matter detection, in particular to an oil bath pot. Background Art

[0002] Plant growth is inseparable from various nutrients in the soil. Soil organic matter contains various nutrients that plants rely on for survival and growth. Soil organic matter is closely related to soil fertility. The higher the organic matter content in the soil, the higher the soil fertility. The organic matter in the soil can not only reduce soil water loss, but also reduce soil viscosity through the combination of various elements, increase the number of plants and animals and microorganisms in the soil, and make the soil soft and permeable, which is suitable for plant survival. Soil organic matter detection has become an important test among many soil tests.

[0003] At present, the commonly used detection method for soil organic matter is the oil bath heating method. This method uses an oil bath pot, that is, the soil to be tested is placed in a test tube or beaker, and then the test tube or beaker containing the soil is placed in the oil bath pot, and the high temperature (temperature reaches 180°C) paraffin or vegetable oil in the oil bath pot is used for heating treatment. After the heating treatment is completed, the test tube or beaker is directly taken out of the oil bath pot. In this operation, since the temperature of the test tube or beaker after high-temperature heating is high, taking it out directly from the oil bath pot may scald the experimenter, which poses a safety hazard.

Thus, in the process of taking the test tube 403, it is ensured that the support plate 2 is located outside the oil bath pot body 1, so that the test tube 403 is located outside the oil bath pot body 1. Compared with directly taking the test tube 403 from the oil bath pot body 1, this method has a simple structure, is easy to operate, and will not contact with the high-temperature paraffin or vegetable oil in the oil bath pot, thereby reducing the risk of burns to the experimenter and improving the safety of the entire experiment.

[0033] In other words, when the support plate 2 is located outside the oil bath body 1, on the one hand, the experimenter will not come into contact with the high-temperature paraffin or vegetable oil inside the accommodating cavity 101 when taking the test tube 403; on the other hand, the high-temperature test tube 403 located outside the oil bath body 1 can be cooled down quickly, thus reducing the risk of scalding the experimenter.
