VDS3000 Distillation of Petroleum Products at Reduced Pressure

Test Method
Determines the range of boiling points for petroleum products that can be partially or completely vaporized at a maximum liquid temperature of 400°C at reduced pressures. The sample is distilled at a controlled, reduced pressure under conditions that are designed to provide approximately one theoretical plate fractionation. Initial and final boiling point is measured and a distillation curve relating volume percent distilled and the atmospheric equivalent boiling point temperature can be prepared.

VDS3000 Manual Vacuum Distillation System

• Conforms to ASTM D1160 and related specifications
• Comes standard with glassware set and accessories kit for “Turn-Key” set up and operation
• Sturdy cabinet composed of aluminum frame and cold rolled steel walls
• Control Unit can easily attach and detach from the main unit offering versatility for laboratory workspace
• Clear protective door provides added safety while allowing the operator full view of the system during testing
• Equipped with digital temperature and vacuum displays for improved
measurement reading and accuracy
• Upgrade to glassware set composed entirely of quartz available upon request

The Koehler VDS3000 Manual Vacuum Distillation System is the latest design for determining, at reduced pressures, the range of boiling points for
petroleum products according to ASTM D1160 and related specifications. The main body of the system or cabinet is composed of an aluminum frame and cold rolled steel walls. The base of the cabinet houses a 5 Liter Stainless Steel Surge Tank to reduce pressure fluctuations during testing. The control unit of the system features a versatile, compact, modern design. Dual temperature displays independently show both the overhead and flask temperature of the system. Built in cooling fan rapidly cools the distilling flask allowing the user to handle glassware and shorten turnaround time in between test runs. Equipped with complete glassware set and accessories kit for “Turn-Key” installation and operation of the Vacuum Distillation System.


The Standard Glassware Set consists of 500mL quartz distilling flask with thermowell, vacuum jacketed distilling column and condenser assembly, water jacketed receiving cylinder, 90° elbow adapter tube, Dewar-Type Cold Trap with 10mL graduated receiver and stopcock drain, PT100 probe adapter, PT100 vapor temperature probe and PT100 flask temperature probe. The system also includes an adjustable scissor jack, heating mantle, retaining springs, ball joint clamps, connection tubing, hose clamps, quick connect adapters and fittings for easy connection of jacketed glassware and tubing and vacuum grease.
