Product Name: BUCHI R 121 Rotary EvaporatorPurpose: It is suitable for solvent evaporation, concentration, and sample purification in fields such as chemistry, pharmacy, and food and beverage. It can be used in laboratory bench - scale and pilot - scale stages and can handle solutions with volumes ranging from 50ml to 3L and above.Performance: It adopts a vertical installation method, and the rotation speed range is 0 - 220rpm. It is suitable for a power supply of 100 - 120V, 85W, 50 - 60Hz. It is equipped with a Buchi 461 water bath with heating function. The power of the water bath is 1200W, and the temperature range is 30 - 100°C. It has a rotation speed/temperature display selection, and the rotation speed and water - bath temperature are presented through a bright digital display. If an optional sensor is equipped, the internal vapor temperature can also be displayed. A drop in vapor temperature can indicate the completion of the distillation process. The height of the heating flask, collection flask, and bump trap can be adjusted.
