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.

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.
