The Automatic Aniline Point Apparatus is designed to characterize pure hydrocarbons and evaluate the aromatic content of hydrocarbon mixtures. Testing involves heating a controlled mixture of aniline and sample until miscibility, followed by cooling to determine the temperature at which phase separation occurs — the aniline point or mixed aniline point.

The apparatus is fully automated, employing a platinum immersion heater for direct sample heating and photoelectric detection for precise endpoint identification. The large LED temperature display ensures clear readings, while a built-in pressure regulator and solenoid valve allow cooling air for accelerated cycles or sub-ambient testing. With refrigerated cooling, aniline points as low as 0°C (32°F) can be determined.

Variable controls for heater, light source, and stirrer speed provide flexibility, and the cabinet is coated with a chemical-resistant polyurethane enamel finish for durability. The system is suitable for samples ranging from clear to very dark, ensuring broad applicability in petroleum and solvent analysis laboratories.
