If the moisture inside the isothermal container is not completely dried, it is indeed possible for bacteria to grow. This is because the growth of bacteria usually requires a certain humidity environment, and the residual water provides such conditions for the bacteria. When the humidity inside the container is too high, some moisture resistant bacteria may begin to multiply, especially at suitable temperatures.
In addition, if a isothermal container has been used to cultivate microorganisms or store other items that may contain bacteria, then bacteria may already be present inside the container. In this case, residual water is more likely to become a breeding ground for bacteria.
Therefore, in order to avoid bacterial growth, it is recommended to thoroughly dry the water inside the container as much as possible after using a isothermal container. Appropriate drying methods can be used, such as wiping with sterile tissue or letting it air dry naturally for a period of time. At the same time, it is also very important to regularly clean and disinfect the isothermal container to ensure its internal environment is hygienic and sterile.
