K87150 VDA7000 Automatic Vacuum Distillation System


Test Method
The sample is distilled at a controlled, reduced pressure under conditions which provide approximately one theoretical plate fractionation. A distillation curve relating volume distilled and boiling point atmospheric equivalent temperature is prepared.

Features and Benefits

• Conforms to ASTM D1160 and ISO 6616 test specifications

• Windows®-based software fully automates data acquisition and analysis

• Operating Range: 0.1 to 760 mm Hg

• Test data is displayed in real-time

• Automatic shutdown and cleaning procedures

• Automatic nitrogen degassing at test conclusion

• RS 232 interface for LIMS connection


VDA7000 Automatic Vacuum Distillation System
The Koehler VDA7000 Automatic Vacuum Distillations System performs reduced pressure distillations of petroleum products, fully automated from the Initial Boiling Point (IBP) to the detected or pre-selected Final Boiling Point (FBP). Advanced Windows®-based software package allows continuous operation at reduced pressure and atmospheric conditions, and the selection of intermediate stops at pre-selected vapor or flask temperatures followed by the continuation of the distillation analysis at various user-selected reduced pressures. The distillate volume is automatically measured in a temperature-controlled receiver, and the heat rate is automatically controlled for a proper distillation rate. All test parameters are displayed during the distillation process in real-time, including actual boiling temperature, AET (atmospheric equivalent temperature), distillation rate, distilled volume, distillation rate vs. yield, and vacuum pressure. Test results, parameters and oil specific data are archived on the computer hard drive, and easily printed to an external printer.
