Viscosity-change-detecting apparatus and stirring rotor

Abstract

A viscosity-change-detecting apparatus 5 comprising (a) an elastically deflectable and/or twistable member 16, and (b) a movable permanent magnet member 13 mounted directly or via a connecting member to the elastic member 16 such that the movable permanent magnet member 13 moves depending on the deformation of the elastic member 16, part of the elastic member 16 being fixed to a support 135 for the viscosity-change-detecting apparatus 5, so that the elastic member 16 is subjected to elastic deflection and/or torsion with rotation and/or vibration in the rotating liquid, whereby the relative position of the movable permanent magnet member 13 to a fixed external detector 6 changes depending on the viscosity change of the liquid, and whereby the change of the relative position is detected by the external detector 6 to detect the viscosity change of the liquid. This viscosity-change-detecting apparatus is suitable for providing the function of detecting viscosity change to stirring rotors, stirring apparatuses, reaction apparatuses and semi-automatic synthesis apparatuses.
