Aldrich® Kugelrohr Short-Path Distillation Apparatus
Quickly Distills the Most Difficult Materials with Minimal Loss
The large air-bath oven and powerful drive train motor are housed within a single unit
with a compact footprint that fits easily into fume hoods or on bench tops.
The oven door has a large glass viewing window and is hinged to open completely for
easy access to glassware during setup and removal. Time, temperature, vacuum and
drive train controls are located on the front splash-proof panel.
The oscillating motion of the drive train eliminates rotary seals that wear out and
enables extremely high vacuum capability.
(Glassware not included.
Order separately.)

Operational Overview
Step 1. Fill load flask one-third full
with distillable material and connect
flask support rod to drive train adapter
inside oven. Connect load flask to a
horizontal ball-tube flask outside oven.
Step 2. Connect straight tube adapter
to ball-tube. Connect to cold trap with
rubber tubing. Connect cold trap to
vacuum source.
Step 3. Turn on Kugelrohr power
switch and drive motor which rotates
distillation train 270 degrees in an
oscillating motion to speed distillation,
assure even heating, and prevent
bumping. Turn on vacuum pump (if
plugged into back of Kugelrohr oven).
Step 4. Set timer and distillation
temperature with the front panel
keypad.
Step 5. Collect distillate in the
horizontal ball-tube outside the oven.
An ice-filled polypropylene cooling
tray quickly condenses distillate.
The adjustable cooling tray support
accommodates larger baths or can be
removed completely as necessary.

Aldrich® Kugelrohr and Chemical Dryer Apparatus
Aldrich® Chemical Dryer
Dries Samples Using Heat, Vacuum, and Desiccant
Precise digital control simultaneously displays both “set” and “actual” temperatures
from ambient to 230 °C. A built-in thermocouple automatically maintains selected
temperature.
The oven features a precision machined aluminium heating block with a borosilicate
glass sample-viewing port and an integrated safety guard to prevent touching hot
parts. The glass drying tube is protected within the enclosed heating block and is
safely contained in the event of accidental breakage. The modular design permits the
removal and storage of dried samples in sealed drying tubes. This enables rapid sample
processing in succession for servicing multiple users.
Specifications:
Accuracy
•Temperature range: ambient to 230 °C
•Calibration accuracy: 0.1% of span
•Temperature stability: 0.2 °F / °F rise in
ambient maximum
•Voltage stability: 0.01% of span / % of
rated line voltage
Power
•50/60 Hz 5%
•Data retention upon power failure
via non-volatile memory
•Detachable power cord
•CE compliant
Operating Environment
•32 to 149 °F / 0 to 65 °C; 0 to 90% RH,
non-condensing
