<p>A rotary evaporator (1), having an equipment stand (2) with a protruding guide tower (3), a glass structure (4) which has an evaporation tank (5) and can be displaced on the guide tower (3) for lifting and lowering the evaporation tank (5) thereof, and at least one fluid line that is connected to the glass structure (4). In one embodiment, the guide tower (3) has a channel (17) that is oriented in the longitudinal extension of the tower (3) and in which a line section is provided of at least one fluid line that is connected to the glass structure (4) and opens out into or ends in a flexible tube connection. This flexible tube connection is arranged on a bottom-side region of the rotary evaporator, which faces away from the free end of the guide tower (3), and the glass structure (4) is retained on a carriage (21) that can be displaced laterally on the guide tower (3). In another embodiment of the invention, the carriage (21) can be displaced from a lifting position against a return force into a lowering position, and a stationary winch (35) located opposite the guide tower (3) is provided for displacing the carriage (21), said winch comprising at least one rope (37) that can be wound up and is retained or guided on the carriage (21).</p> |
