Kugelrohr apparatus shown with KNF Laboport vacuum pump (sold separately).
- 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
|
• Distills the Most Difficult Materials •
|
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 bumping. Start the vacuum pump.
*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
|
When the correct vacuum is attained, set the distillation temperature on the air-bath oven and begin distillation. The digital temperature controller displays both "set" and "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. |
