Is it better to use waterproof incubator or electric heating incubator for bacterial culture?

We are all very familiar with the incubator. The cultivation, reproduction, fermentation and constant temperature experiment of bacteria are inseparable from the constant temperature incubator, which is widely used in our biology, medical care, agriculture, scientific research and universities. You may be very familiar with its function and use. At present, there are many kinds of constant temperature incubators, among which we commonly have electrothermal constant temperature incubators, waterproof constant temperature incubators, biochemical incubators, molds and so on. Each has its own characteristics and uses. This paper introduces the differences and characteristics of two incubators. First of all, we are talking about an electric constant temperature incubator. As the name implies, it uses electric heating. The shell of the electrothermal constant temperature incubator is made of cold-drawn plate by electrostatic spraying, the inner container is made of stainless steel, the insulation layer is made of asbestos, and the bottom is provided with a heating pipe, through which the interior of the incubator is heated. Its disadvantages are relatively poor temperature uniformity and large temperature shock. Secondly, the waterproof incubator, from the name we can also see that it is related to water. Some people will say that the waterproof incubator should be kept away from water when used. This understanding is just the opposite. Waterproof incubator can only work with water. From the appearance, it seems to be no different from the ordinary electrothermal constant temperature incubator, but their working methods are quite different. The waterproof incubator has a water inlet and an overflow on the side of the box for adding water. The material of the shell and the inner container is the same as that of the ordinary constant temperature incubator, but the inner container is a waterproof incubator with a water storage interlayer made of copper skin. The heating tube heats the water in the interlayer, and the convection of water forms four-sided heating, which effectively ensures the heating uniformity. Through the above distinction, I believe everyone has a new understanding of waterproof constant temperature incubator and electric constant temperature incubator. Electrothermal incubator is widely used because of its simple structure and relatively low price. Waterproof incubator is undoubtedly a better choice for experiments with high temperature requirements or high heating uniformity requirements.
