The sample aniline mixture is directly heated by a platinum immersion heater, and the aniline point is detected photoelectrically.
Temperature is displayed on a large LED indicator.
Built-in pressure regulator and solenoid valve permit the use of cooling air for quicker cooling cycles or to determine subambient aniline point temperatures. Equipped with variable controls for heater, light sources, and stirrer speed. Cabinet exterior surfaces have chemical resistant polyurethane enamel finish. Aniline point is used to characterize pure hydrocarbons and to indicate the aromatic content of hydrocarbon mixtures. After the two phases become miscible, the mixture is cooled at a controlled rate and the temperature at which the two phases separate is the aniline point or mixed aniline point of the sample.
