[0002] A water bath is an essential tool for educational and scientific research in biology, genetics, virus, aquaculture, environmental protection, medicine, hygiene, biochemistry laboratories, and analytical rooms. A high and low temperature circulating water bath is a type of water bath. People place containers containing test solutions into the water bath to heat the test solutions. These containers containing test solutions are mostly glassware with flat bottoms, such as conical flasks and beakers. When the test solution is placed in containers with spherical bottoms, such as test tubes, these containers cannot be placed stably in the water bath.
