 K45603 Automatic Distillation Analyzer 5000 Series
The Koehler Automatic Distillation Analyzer is designed to perform optimal distillation analyses of gasolines, fuels, oils, solvents, aromatics, napthas, kerosenes, hydrocarbons, and other volatile products to ensure conformity to rigid quality control standards. The analyzers automatically perform tests, process results, and produce standard reports according to ASTM, ISO, DIN and related international test specifications.

Each Koehler Automatic Distillation Unit comes ready with the equipment, accessories, and features as standard to properly run distillation groups 0 to 4 per ASTM D86 and related test specifications. No additional accessories are required. The Windows®-based software package allows simple operator selection of the programmed settings for each distillation protocol. No complicated routines are needed to setup the unit. User-defined programs are easily created for customization of the analyzer.

Dry Point can be detected visually or by automatic detection for ASTM D850 and D1078 test methods. The unit is delivered ready with the PC board components already included as standard to perform the dry point analysis. It only requires the additional accessories of the dry point thermocouple, 200mL flask, and PTFE plug in order to perform the dry point detection analysis automatically.

Conforms to the specifications of:
ASTM D86, D285, D850, D1078, D4737; D189 Section 10; DIN 51751; ISO
3405; IP123; JIS J2254; NF M 07-002
Electrical requirements:
120V 50/60Hz 20A
230V 50/60Hz 10A
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 15 mL/min in 0.1mL increments, user selectable
Receiver Volume: 0 to 100 mL (±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
Barometric Pressure: Automatic barometric correction utility with
automatic sensor, range 550 to 900 mm Hg (±1mm Hg accuracy)
Dry Point Detection: Dry point detection board is included with standard
equipment and only requires a dry point sensor, 200 mL flask and PTFE plug for ASTM D850 and D1078 tests.
Environment: Operates at 0 to 45°C (113°F)

Two Models are Available
The Automatic Distillation Analyzer 5000 series may be ordered for operation with an external PC (purchased separately) or may be ordered with a built-in PC, internal touch screen monitor, virtual keyboard and mouse. An easy-to-use Windows®-based PC communication software expands user capabilities for data analysis and unit control. Distillation methods and parameters can be easily created or modified. Software calculates repeatability and reproducibility as per ASTM D86 as well as standard and deviation against reference materials. Test results are displayed in real-time and can include distillation curve and temperature with or without barometric compensation and/or evaporation correction, distillation rate, heating power curve, master curve comparison, and zoom function for high resolution of heating and temperature curves. The heater compartment is rapidly cooled at the completion of a distillation run to reduce operator downtime. The analyzers are of rugged construction for instrument longevity with a modular design for easy routine maintenance.

Receiver Chamber Heating System
The receiver chamber heating system is ideal for samples that form waxes or other solids during distillation.
