A water bath is one of the most basic tools in a laboratory. It is used for testing samples at the desired temperature for a long time. The user can adjust the desired temperature with digital control panel (LED). A water bath can be divided into 3 main components: A heating unit, a stainless steel chamber in order to holding the water and samples and the control panel. It is needed in various areas including; incubation, material, corrosion tests, temperature control applications of the cultivates, food and beverage tests and so on… The inner chamber is completely smooth and there is no any prevented tool for transportation of the samples. Therefore, the whole inner surface can be used safely for temperature control even with small sample containers.
The design and sizes of the water baths are various. The capacity of a standard model is between 12-35 liters. All water baths can be work until 100°C although, if the needed temperature is higher than 100°C, oil bath or silicon oil should be prefered. For different solutions, there are shaking and rotating water baths as well.
The user had better check if there is water or not in the inner chamber. When the water bath is in operating, there must be a certain amount of water so that the water bath can be protected against burns and in case of overheating. If there is a little or no water, a sufficient amount of pure water should be added or the extra pure water shoud be drained. Pure water is very important for a long-life water bath because it reduces situations like calcification and prevents possible contamination.
