This Buchi RotaVapor R-II Rotary Evaporator features a vertical condenser assembly, allowing for standard distillations and the handling of high-boiling solvents exceeding 100°C. The R-II cools with tap water, and includes an inlet feed tube that allows for the continuous feeding of volumes that exceed the flask capacity.

The Buchi rotary evaporator uses a manual quick-action jack for ease of operation, and the combi clip facilitates the removal of the flask and dismantling of the vapor duct. The continuous vapor duct comes with a PTFE composite vacuum seal, ensuring efficient performance. With an adjustable angle from 0° to 25°, the rotation speed ranges from 20 rpm to 280 rpm, and can handle a maximum flask capacity of 3 kg. The temperature range is between 20°C and 95°C, with an accuracy of ± 5°C.

The RotaVapor R-II features a display scale 0 to 10, while the B-100 heating bath displays scale 0 to 100°C and on/off status of heating. The design incorporates powder-coated aluminum for durability and a kettle connector between the bath base and the heating bath.
