Abstract
An elevational operating device for a rotary evaporator comprises a pole, an elevating member which rotatably supports a sample vessel and which is mounted at its base portion to the pole to freely and vertically move, and an elevational operating pipe mounted in parallel with the pole to elevate the elevating member by the rotation of the pipe. The elevational operating device is by further provided a nut member adapted to be threadably inserted into the elevational operating pipe. The nut member is inserted into an inserting hole formed in said elevating member with a clearance for allowing a small and relative motion.
