SED-2ZFY-B Rotary Evaporator. Lab-scale equipment for purification distillation: under negative pressure, the rotary flask is heated by a constant-temperature bath, rotation forms a thin film for high-efficiency evaporat
Como funciona
Rotary flask (0.5–2 L) immersed in a heating bath rotates at 0–120 rpm (manual) or 10–120 rpm (electric) to form a thin liquid film over the inner glass surface. Bath maintains setpoint via PID control (water bath up to 199°C; oil bath up to 180°C, independent power switch). Vacuum pump (external, via Ø10 mm hose) applies up to -0.098 MPa, lowering the boiling point. Solvent vapor rises through the rotation joint into a vertical double-coil condenser (0.15 m² surface) where it condenses; condensate collects in a 1 L receiver. PTFE composite seal at the rotation joint maintains vacuum integrity. Bath separates from main unit for flexible configuration.
