Distills the Most Difficult Materials
  • Distills heat-sensitive compounds
  • Distills liquids and low-melting solids from polymers and tars
  • Distills with minimal holdup and sample loss
  • Removes color and particulates
  • Can be used for sublimation/solvent evaporation




Typical operation

Step 1
Fill the load (oven) flask (25 mL to 2 L) one-third full with distillable material. Connect the load flask to the motor drive coupling inside the oven. Connect the load flask to a horizontal receiving flask outside the oven. Connect a straight tube to the receiving flask and to a vacuum source with rubber tubing.
Step 2
A vacuum pump may be plugged into the receptacle on the rear of the oven and switched on and off from the Kugelrohr front control panel.

*Use of a vacuum trap between the rotary drive and the pump is recommended to protect the pump. See the Equipment Section of the Aldrich Handbook for vacuum traps.
Step 3
Fill cooling tray with ice.
Step 4
Turn on the Kugelrohr main power switch. Set the distillation temperature on the front control panel, turn on the motor drive and vacuum pump.
Step 5
Collect distillate in the horizontal receiving flask outside the oven.View this video to get an overview of the Kugelrohr features.
