Aniline Point Apparatus

The Aniline Point Apparatus manufactured by Glass Agencies is widely used in petroleum testing laboratories, research institutions, and quality control departments for determining the aniline point of petroleum products such as lubricating oils, diesel fuels, and other hydrocarbon mixtures. The aniline point is defined as the lowest temperature at which equal volumes of aniline and the petroleum sample become completely miscible. This test helps determine the aromatic content of petroleum products, which is important for evaluating their chemical characteristics and performance in industrial and automotive applications. The apparatus allows laboratories to perform this analysis under controlled conditions to obtain reliable results. The Aniline Point Apparatus works by placing equal quantities of the petroleum sample and aniline in a special test tube or vessel provided with the apparatus. The mixture is gradually heated while being stirred to ensure proper mixing of the two liquids. As the temperature increases, the liquids begin to dissolve into each other. The mixture becomes completely clear at a particular temperature, indicating that the two substances have become fully miscible. After reaching this stage, the mixture is allowed to cool slowly while being observed carefully. The temperature at which the mixture first shows separation or cloudiness during cooling is recorded as the aniline point of the sample. This value provides useful information about the composition and aromatic content of the petroleum product being tested. Glass Agencies manufactures the Aniline Point Apparatus using carefully selected materials suitable for petroleum testing laboratories. The apparatus is constructed to provide stable heating conditions and clear observation during the testing process. The components include a heating arrangement, sample tube holder, thermometer support, and a stirring mechanism that helps maintain uniform mixing of the liquids during the experiment. . The Aniline Point Apparatus is commonly used in petroleum laboratories, oil refineries, fuel inspection departments, and research facilities where petroleum products are analyzed for quality control. It supports the evaluation of chemical properties of fuels and lubricants.
