20L Stainless Steel Short Path Distillation Kit with Dual Layer Cold Trap

Lab1st SPD-S series short path distillation kit offers a durable and reliable solution for purifying small amounts of compound or distilling materials that are unstable at high temperature. Compared to SPD-20N, model SPD-20S short path distillation kit is more durable as it's with a stainless-steel cold trap. The glass cold trap uses one layer for the chilling effect, while stainless steel one adopts two layers to make the fluids chill at a double rate by largely increasing the condensing area. 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 discharging 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 bet
