Antique Duboscq Colorimeter
From Bausch and Lomb

w/ Accessories

Equipment Notes:

This is an Antique Duboscq Style Colorimeter made by Bausch & Lomb some time in the mid 1940's. They were very common lab instrumnets, used to compare the refractive index of a known liquid against an unknown one. I think it has all of its parts and accessories. It is very well made and seems to be working perfectly. It comes with a nice wooden box / case.

The colorimeter was introduced by the French Artisan and Optical Instrument maker Jules Dubosq in 1854 later produced by the French Instrument factory Pellin. The instrument was mainly used to characterize different substances in the blood through optical differences between the sample and a standard. However the instrument could be used to indicate Hydrogen concentration in water with aid of an indicator.
