The automatic aniline point apparatus, available from Particle Test , 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 0°C (32°F) can be determined with the use of refrigerated cooling air.
The apparatus is equipped with variable controls for heater, light source and stirrer speed. Cabinet exterior surfaces have a chemical resistant polyurethane enamel finish.
- Conforms to the specifications of ASTM D611; IP 2; ISO 2977; DIN 51775; FTM 791-3601; NF M 07-021
- Testing range: 0 to 150°C (32 to 302°F)
- Temperature display: 0-999.9°C
Aniline point is used to characterise 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.
Features and benefits:
- Conforms to ASTM D611 and related specifications
- For samples ranging from clear to dark
- Temperature range 0° to 150°C (32 to 302°F)
- Digital temperature display
