Vacuum Rotary Evaporator With Quick Action Jack (Buchi Type)  (New improved model with variable system and D.C. MOTOR but to work on 220 volt A.C.) The apparatus consists of an Evaporating Flask rotated by non-sparking electric motor in heating water bath. The drive unit is clamped on V SHAPED heavy duty stand. The introduction tube permits continuous feed of the liquids into evaporating flask and also distillation under controlled atmosphere.The evaporating flasks is pear shaped to give a large surface area for evaporation, clamped to a glass duct which goes through the drive unit and produced into the condenser. The top condenser is fitted with B-19 joint through which introduction tube is inserted. The condenser spherical joint S-35 at the bottom of the condenser to receiver flasks cap; 1 Litre of Corning Glass with Ball point socket. The Condenser is Double Coil for Cooling Water and suitable for 220 volts, 50 cycles A/C Complete unit is fitted on V shape Heavy Duty Stand with Quick Jack Action CAP.
