具有带有夹紧元件的紧固装置的旋转蒸发器
摘要：
本发明涉及具有旋转驱动器和紧固装置的旋转蒸发器，该紧固装置附接到旋转驱动器并且具有用于容纳可由旋转驱动器旋转的蒸发活塞的容纳腔室，其中紧固装置包括在旋转驱动器侧的特别是环形附接部分(11)，和在蒸发活塞侧的特别是环形套环元件(17)，该套环元件(17)耦合到附接部分(11)并且可相对于附接部分(11)在起始位置和终止位置之间旋转。紧固装置包括至少一个夹紧元件(31)，在套环元件(17)相对于附接部分(11)从起始位置到终止位置的旋转期间，夹紧元件(31)从释放位置径向向内地移动到保持位置，在保持位置中相应的夹紧元件(31)突出到容纳腔室中，以用于容纳在紧固装置的容纳腔室中的蒸发活塞的凸缘形附接点，以完全锁定和/或非完全锁定的形式被保持并且被固定以防止从容纳腔室移除。
摘要（英）：

The invention relates to a rotary evaporator comprising a rotary drive and a fastening device attached to the rotary drive and having a receiving space for receiving an evaporator flask rotatable by the rotary drive, wherein the fastening device comprises a connector section, in particular a ring-shaped connector section, at the rotary drive side and a retainer element, in particular a ring-shaped retainer element, at the evaporator flask side that coupled to the connector section and that is rotatable relative to the connector section between a starting position and an end position. The fastening device comprises at least one clamping element that is moved, on the rotation of the retainer element relative to the connector section from the starting position into the end position, from a release position radially inwardly into a holding position in which the respective clamping element projects into the receiving space to hold a flange-shaped connection region of an evaporator flask received in the receiving space of the fastening device in a form-fitting and/or force-fitting manner and to secure it against a removal from the receiving space.
