Performs aniline point and mixed aniline point determinations automatically by means of a modified thin film technique (ASTM D611 Method E). 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. Aniline points as low as 21°F (-6°C) can be determined with the use of refrigerated cooling air. Equipped with variable controls for heater, light sources, and stirrer speed. Optional modified Pyrex^TM cell (Part number K10211) permits the testing of extremely dark samples, including some refinery gas oils, that are too dark to be tested in the standard sample cell. 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.

Equal volumes of aniline and sample or sample plus n-heptane are stirred together while being heated at a controlled rate.

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.
