20L Short Path Distillation Kit with Vac Pump, Heating Mantle and Heating Cooling Circulator

Lab1st SPD-N series short path distillation unit offers a cost-effective and reliable solution for purifying small amounts of compound or distilling materials that are unstable at high temperature. Model SPD-20N has a 20L boiling flask and new design distillation head that is made with high borosilicate glass. It is also equipped with receiving flask with valves instead of 1-to-1 or 1-to-3 flask, ensuring a vacuum environment and continuous discharge, and the newly re-designed distillation head with larger vacuum jacket can reduce heat loss during distillation.  Advantages:  Newly re-designed distillation head with larger vacuum jacket for less heat loss during distillation, increased internal diameter for more efficient distillation. Using receiving flask with valves instead of 1-to-1 or 1-to-3 flask, which guarantees the vacuum environment and realizes continuous discharge. Using thermowell instead of screw adapter, ensuring no gas leakage Using KF25 flange and flexible stainless
