Manual Lifting Rotary Evaporator LMRE-A20

Manual Lifting Rotary Evaporator LMRE-A20

Manual Lifting Rotary Evaporator LMRE-A20 is 5 L heating bath with a wide temperature ranges from room temperature to 180°C. The speed ranges from 20 to 200 rpm, timing interval operation in clockwise and anticlockwise directions for drying process. Rotary evaporator design is composed of standard set of heating bath, set of glassware, vertical 1000 ml evaporating flask (NS 29/32) and receiving flask (KS 35/20). The manual lift is combined with an auxiliary lift for precise positioning of the glassware. Others like Vacuum pump, Low temperature circulator, Vacuum controller are optional accessories. Designed with LED display to observe speed, temperature and time. It is basic chemical laboratory instrument suitable for evaporation, distillation and separation of chemicals.
