The constant temperature water bath is mainly used for the precise control of a certain temperature required for the sample to be heated, so as to compare different samples in the same temperature control environment, or the same sample at different temperatures in different states. Comparison. Since the water in the constant temperature water bath is at rest, there will be a small temperature difference at different points. The water bath is generally used to heat the triangular flask. Without removing the cover of the water bath, only a triangular flask with a capacity of not more than 1000ml can be used.
Shanghai Haozhuang Instrument Co., Ltd. LNB brand constant temperature water tank has the characteristics of internal and external circulating water flow. When using a triangular flask with a capacity of 1000ml-5000ml, due to its large bottom area and high height, the phenomenon of uneven water temperature is more serious. In the case of high temperature uniformity, it is necessary to add a circulation pump to force water circulation to improve the uniformity of water temperature. Another use is to use its external circulation characteristics to establish a second constant temperature field. The main difference between the constant temperature water bath and the constant temperature sink is the uniformity of the water temperature. The uniformity of the water temperature of the water bath (≤0.5 ° C) and the uniformity of the constant temperature water temperature (≤0.05 ° C) Range of use.
