Abstract: A rotary evaporator including a rotating flask (2) to hold the substances to be evaporated, and a drive (6) to rotate the rotating flask around an axis of rotation (R) that runs through the rotating flask, wherein the rotating flask additionally can be swiveled around a swiveling axis (S) which runs outside of the rotating flask and, relative to the force of gravity (G), runs above the axis of rotation of the rotating flask.

Abstract: A sealing device for sealing a cavity (40) that can be rotated around a rotational axis (A) and including at least two sealing areas separated from each other by at least one intermediate zone (Z1 to Z3); two sealing faces (20, 21 to 24, 30, 31 to 33, 41, 71 to 74) continuously extending around the rotational axis and slidingly movable over each other upon rotation of the cavity (40), and at least one connection (A1 to A3, B1 to B3) for charging, discharging, or passing fluids into, out of, or through the at least one intermediate zone, respectively.
