Kugelrohr short-path distillation apparatus

Distills the most difficult materials!

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

Step 1. Oven flask is filled one-third full with distillable material, placed carefully in oven, and connected to the horizontal receiving flasks outside the oven.
Step 2. Connect the glassware to the rotary drive and the drive to a vacuum pump. *Switch the vacuum drive on to turn the distillation train 360° to speed distillation, ensure even heating, and prevent pumping. Start the vacuum pump.
Step 3. When the correct vacuum is attained, set the distillation temperature on the air-bath oven and begin distillation. The digital temperature controller toggles from "set" or "actual" air-bath temperature.
Step 4. Collect distillate in the horizontal ball-tubes outside of oven. An ice-filled polypropylene cooling tray quickly condenses distillate in receiving ball-tubes.

_{*Use of a vacuum trap between the rotary drive and the pump is recommended to protect the pump.}
