<p>#CMT# #/CMT# The evaporator has a clamping insert (29) including a clamping sleeve for clamping a vapor duct (15) i.e. hollow glass shaft, in a hub (27) of a rotation drive. The clamping insert has a longitudinal axis and two axial ends. The clamping insert has two clamp sections (39, 41) that are spaced apart from each other in a longitudinal direction. The clamp sections have an outer cross-section that tapers at one of the ends. One of the clamp sections (41) has a large maximal outer cross-section and is arranged closer to the other end. #CMT#USE : #/CMT# Rotary evaporator for use as a laboratory apparatus. #CMT#ADVANTAGE : #/CMT# The clamp sections are spaced apart from each other in the longitudinal direction, and have the outer cross-section that tapers at the respective axial end, where one of the clamp sections has the large maximal outer cross-section and is arranged closer to another axial end, thus increasing service life of a sealing ring provided between a cooler connection of a stationary cooler and a cooler-sided end of the vapor duct. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an enlarged sectional view of a region of a hub of a rotation drive of a rotary evaporator. 15 : Vapor duct 27 : Hub 29 : Clamping insert 39, 41 : Clamp sections 59 : Front contact section 69 : Rear contact section.</p> |
