Rotating plastic evaporator - with plastic coupling tube - bearing on spherical section moving seal
Реферат: An inclined rotating distillation flask, is coupled to a glass condenser via pref. PTFE coupling tube, fitted to the flask by a grooved conical male joint, and rotating on a spherical section seal at the condenser. Rotary movement is induced at a metal sleeve around the coupling tube. The moving seal is not spoilt by wear or solvent action, so that leakage is minimal down to 10-3 Torr vacuum, at distillation temperature =250 degrees C, even after long use. Plastic conical joint is easily sepd. from flask after distillation.
