    Patent number: 5821407
    Abstract: An off-line automatic viscosity measuring apparatus, which can execute viscosity measurement of a plurality of specimens while automatically replacing rotors, is provided. The off-line automatic viscosity measuring apparatus according to the invention has: a detachable rotor 7; a viscosity detection head 33 for executing viscosity measurement with the rotor 7 connected thereto; a detection head moving mechanism 34 for moving the viscosity detection head 33 up and down and left and right; a separation aid mechanism 50 for aiding in separation of the rotor 7 and the viscosity detection head 33; and a rotor magazine mechanism 40 for holding a plurality of rotors 7. The viscosity detection head 33 has a bottom end formed with a detection head attaching/detaching part for accepting the rotor 7. The rotor 7 has a top end formed with a rotor side attaching/detaching part being inserted into the detection head attaching/detaching part for connecting the rotor 7 and the viscosity detection head 33.
