Abstract

A cylindrical support and centering device for a sensitive viscometer comprises a hollow cylindrical support member open at opposite ends. The viscometer is supported on the upper end with its cylindrical pivot housing slip-fitted into the upper end in snug contact with an inner cylindrical surface of the support. The pivot housing either rests against an annular stop surface formed below the cylindrical surface or is supported by contact of the viscometer with the upper end. The lower end of the support is dimensioned to snugly engage the outer cylindrical surface of the stator so that the longitudinal axis of the stator is coaxial with the longitudinal axis of the rotor for precise centering.
