Abstract
Description
Technical Field

[0002] The density bottle method is a classic method for determining the density and relative density of liquid chemical products. The test principle is to calibrate the volume of the density bottle with water at the same temperature, and then measure the mass of the sample of the same volume to find out its density. When testing again, fill the density bottle with pure water cooled to 20℃, without bringing in bubbles. After filling, immediately immerse it in a constant temperature water bath of 20℃±0.1℃, keep the constant temperature for more than 20 minutes, take it out, use filter paper to remove the water overflowing the capillary, wipe it dry and weigh it immediately. Pour out the water in the density bottle, wash it, dry it and weigh it. Replace water with the sample, perform the same operation as above, and measure the mass of the sample. The density of the sample is obtained by calculation.
[0003] In actual use, most of the prior art uses a constant temperature water bath to heat the density bottle. However, since the water tank of the constant temperature water bath can only be set to the same temperature, it is not possible to simultaneously carry out density measurements at multiple temperature points, and the efficiency is low. In addition, during the heating process of the existing digital display water bath, the heated water in the pot has a large buoyancy, which makes it impossible for the vessel to be placed stably on the receiving plate, resulting in overflow of the test solution, thereby affecting the test results.
