Specification of Koehler K45604 ADA5000 Automatic Distillation Analyzer

Test Method

The sample is evaporated and condensed under controlled conditions, and observations are made of the temperatures at which various percentages are recovered and/or the percentages recovered at specific temperatures.


Conforms to the specifications of: ASTM D86, D285, D850, D1078, D4737; D189 Section 10; DIN 51751; ISO 3405; IP 123; IP 195; JIS K0066; JIS K2254; NF M 07-002

Temperature Distillation Range: 0 to 450°C (±0.1°C accuracy)

Condenser: -5 to 60°C (±0.1°C accuracy); closed loop system

Receiver Chamber: 0 to 60°C (±0.1°C accuracy)

Distillation Parameters:

Distillation Rate: 2 to 15mL/min in 0.1mL increments, user selectable

Receiver Volume: 0 to 100mL (±0.01mL accuracy) by photoelectric infrared detection of meniscus by level following system utilizing a precision stepper motor and a special calibrated glass receiver; automatic calibration of evaporated loss volume and automatic volume calibration system ensures highest accuracy

Barometic Pressure: Automatic barometric correction utility with automatic sensor, range 550 to 900 mm Hg (±1 mm Hg accuracy)

Dry Point Detection: Automatic dry point detection board is included with standard equipment and only requires a dry point sensor, 200mL flask and PTFE plug for ASTM D850 and D1078 tests.

Environment: Operates at 0 to 25°C (113°F)
