Fully Automatic Vacuum Distillation System, processor controlled according to ASTM D-1160 with automatic fraction collector for the determination of boiling ranges of crude oil products under vacuum. The system can be operated in strict accordance to the ASTM procedure with 1 single receiver or alternatively, by using the automatic fraction collector, with 4 receivers. The distillation is fully automatic from the initial boiling point to the pre-selected end boiling point or detected break-off. The distillation volume is measured automatically in receivers, temperature controlled by an IR-heater. The yield is calculated in percentage to the charge quantity. Distillation report, final data and distillation curve are printed out.
