Description

Rotating disk viscometer, accession no. 53; 1922

Rotating disk viscometer of MacMichaeil type, used in Dr. Alexis Carrel's laboratory in the 1920s by Dr. Pierre Lecomte du Noüy . In this instrument, viscosity is determined by resistance to the rotation of a metal cone immersed in liquid. The disk is suspended by a torsion wire bearing a tiny mirror to record the twist in the wire caused by the viscosity.
