Koehler K10290 Automatic Aniline Point Apparatus

Spesifikasi Koehler K10290 Automatic Aniline Point Apparatus

Test Method

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.

Specifications

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

Features

• Conforms to ASTM D611 and related specifications
• For samples ranging from clear to very dark
• Temperature range 0°C to 150°C (32°F to 302°F)
• Digital temperature display

Description

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. Equipped with variable controls for heater, light source and stirrer speed. Cabinet exterior surfaces have a chemical resistant polyurethane enamel finish.
