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 steel vacuum bellow instead of barb adapter and silicone hose, for better vacuum environment The entire kit of SPD-20N includes all you need as below: Glassware kit and all accessories * 1 set 20L Magnetic Stirring Heating Mantle* 1 set Desktop precise heater/chiller, 15L reservoir, -5 to 95C * 1 set Rotary vane oil pump, 10 CFM (4L/s), 2-stage * 2 sets Vacuum gauge* 2 sets Insulation jacket* 1 set Apart from 20L volume, we also provide 2L, 5l and 10L options.
