Difference between constant temperature water tank and constant temperature water bath pot and their respective uses

The constant temperature water tank has the characteristics of circulating water inside and outside. In the use of the triangular flask with a capacity of 1000ml-5000ml, due to its large bottom area and high height, the water temperature unevenness is more serious. At this time, the temperature uniformity is required to be higher. Next, it is necessary to add a circulation pump to force the water circulation to increase the water temperature uniformity. Another use is to use the characteristics of the outer loop to create a second constant temperature field. The main difference between the constant temperature water bath and the constant temperature water tank is the water temperature uniformity, the water bath pot water temperature uniformity (≤0.5°C), the constant temperature water tank uniformity (≤0.05°C), and the constant temperature water tank increases the external circulation function, which greatly expands. Use range.

The constant temperature water bath is mainly used to accurately control the temperature required for the sample to be heated, so as to compare different samples in the same temperature control environment, or different states of the same sample at different temperatures. Comparison. Since the water in the constant temperature water bath is at rest, a small temperature difference occurs at different points. The water bath is generally used to heat the flask. Only the flask with a capacity of not more than 1000 ml can be used without removing the cover of the water bath.
