Background

Agar culture is a common method in various biological experiments, and usually, a triangular flask is adopted to contain melted agar for preparing an agar culture medium, required heat-labile nutrient components, antibiotics and the like are added after the temperature is reduced to a certain degree, the agar culture medium is uniformly mixed and then quickly subpackaged into a culture dish, and finally, the agar culture medium is obtained by cooling and coagulating. The preparation method of the agar culture medium has the following disadvantages: firstly, an operator is required to have more experience, the operator can accurately feel the cooling degree of the heated agar by hands, nutrient components and antibiotics can be reduced or inactivated when the temperature is too high, the agar can be condensed and can not be added to the nutrient components and the antibiotics to be uniformly mixed when the temperature is too low, and even the agar can not be poured out. Secondly, the temperature of the agar which is usually melted is reduced to about 50 ℃, and nutrient components or antibiotics are immediately added and mixed evenly; if the indoor environment temperature is low, the melted agar can be gradually solidified in the process of subpackaging the melted agar into culture dishes one by one, so that the agar can not be poured out any more, and can be re-heated and melted, and the nutrient components and the antibiotics can be re-added. Thirdly, pouring the split agar into the plates needs to accurately control the pouring amount, and the amount of the agar added into each plate needs to be basically the same; however, since the Erlenmeyer flask is small at the top and large at the bottom, and it is difficult to grasp the amount of the agar poured out when the Erlenmeyer flask is in an inclined state, it is generally empirically estimated from the amount of the agar which has been poured into the petri dish and is not uniformly spread out. Therefore, it is highly desirable to invent a device that integrates the heating of melting agar, constant agar temperature, and the quantitative addition of agar.
