摘要： A rotary evaporator (1), to which a clamping insert (59) having a sleeve-like base shape is associated for clamping a vapor feed-through, in the form of a glass hollow shaft (8), in the hub (58) of a rotational drive (57). The clamping insert (2) includes clamping sections (K1, K2) which are spaced apart in the longitudinal direction and carry each at least one clamping slope (63, 64) which is beveled relative to the longitudinal axis of the clamping insert (59). The beveled clamping inclines interact with the associated counter inclines (65, 66) of the rotational drive (57) such that the clamping sections (K1, K2) are pressed against the glass hollow shaft (8) when axial pressure of the clamping insert (59) is applied. In one embodiment of the invention, the clamping insert (59) has supporting webs (60) which are oriented in the longitudinal direction thereof, the supporting webs being connected to each other via connecting webs (61, 62) which are oriented in a circumferential direction of the clamping insert (59). The connecting webs (61, 62) alternately connect to each other the web end regions of adjacent supporting webs (60), which are arranged either on the one or the other side of the clamping insert (59). The supporting webs (60) and the connecting webs (61, 62) are connected to form the sleeve-like base shape of the clamping insert (59) such that the spaced apart clamping sections (K1, K2) are formed by the connecting webs (61, 62) which are provided at the opposite ends of the clamping insert (59) and support the clamping inclines (63, 64). In another embodiment of the invention, the sealing ring (76) is designed as an annular disk, wherein the outer annular zone (78) of the annular disk is provided as a clamping edge, the annular disk has an inner annular zone (79) which is folded or angled in the longitudinal direction of the glass hollow shaft (8), and the sealing ring (76) bears sealingly against the glass hollow shaft (8) with a partial region (T) of the annular disk, this partial region being oriented in the longitudinal direction of the glass hollow shaft (8).
