Abstract: A rotary evaporator comprising a motor, a rotary joint movably inserted to a motor rotor of the motor by a sleeve in an axial direction, a collection flask attached to the rotary joint at one end of the joint, with a condenser attached to the other end of the joint. The condenser is adapted to receive a cooling coil from an immersion cooler. The cooling coil is attached to the base unit of the immersion cooler via an insulated hose. The rotary evaporator is adapted to provide various ways to remove heat from the flask in the water bath, whether by mechanically lowering the water bath, dropping fluid from the bath into an underlying reservoir, or raising and lowering the rotary evaporator out of the bath. Where the rotary evaporator is raised and lowered, the immersion cooler can remain in place if the hose connecting the base unit to the cooling coil is sufficiently long, or the condenser includes a flexible portion that accommodates the upward and downward movement.
