Abstract
The invention relates to a rotary evaporator comprising a rotary drive having a hub and a clamping insert with a sleeve-like basic shape, in particular a clamping sleeve, for the clamping of a steam leadthrough formed as a hollow glass shaft in the hub of the rotary drive, wherein the clamping insert has a longitudinal axis and a first and a second axial end, wherein the clamping insert has two clamping sections which are arranged spaced apart from one another in the longitudinal direction and which each have an outer cross-section tapering toward the first end and of which the clamping arrangement arranged closer to the second end has a larger maximum outer cross-section.

A rotary evaporator comprising a rotary drive (11) having a hub (27) and a clamping insert (29) with a sleeve-like basic shape, in particular a clamping sleeve, for the clamping of a steam leadthrough (15) formed as a hollow glass shaft in the hub (27) of the rotary drive (11), wherein the clamping insert (29) has a longitudinal axis (31′) and a first and a second axial end (35, 37),
- characterized in that
- the clamping insert (29) has two clamping sections (39, 41) which are arranged spaced apart from one another in the longitudinal direction (31′) and which each have an outer cross-section tapering toward the first end (35) and of which the clamping section (41) arranged closer to the second end (37) has a larger maximum outer cross-section.
A clamping insert (29) having a sleeve-like base form, in particular a clamping sleeve, for the clamping of a steam leadthrough (15) formed as a hollow glass shaft in a hub (27) of a rotary drive (11) of a rotary evaporator (9), having a longitudinal axis (31′) and having a first and second axial end (35, 37),
- characterized in that,
- the clamping insert (29) has two clamping sections (39, 41) which are arranged spaced apart from one another in the longitudinal direction (31′) and which each have an outer cross-section tapering toward the first end (35) and of which the clamping section (41) arranged closer to the second end (37) has a larger maximum outer cross-section.
