Colorimeter, after a design by Labilliardiere with modifications by Salleron, 1871. The intensities of colour of two liquids in glass tubes are made equal by adding water to the stringer and measuring the volume of water added. The instrument is used in chemical analysis to determine the concentration of solutions by comparison with a standard control. | |
