Photoelectric Apparatus; Rectangular black metal box, hinged lid, The apparatusis divided into two (2) main parts, the registering and the recording systems. The instrument is used to record progressive processes including the coagulability of the blood, the determination of prothrombin, quantitative estimation of fibrin, the sedimentation of erythrocytes and, the quantelation of the Wassermann reaction.

Kaare K. Nygaard (1903-1989) was a surgeon and sculptor from Norway who spent a residency at the Mayo Clinic, moved to White Plains (N.Y.) in 1940, and developed a photoelectric device to measure blood coagulability. An inscription on this example reads “I. ALNAES A/S OSLO / ...; NYGAARD-FALCH / COAGELGRAPH.”
