Ebulliometer - malligand et fils - Brass - 1850-1900 - Ebulloscope

An ebulliometer, specifically a Malligand et Fils brass ebulloscope from 1850-1900, is a scientific instrument used to determine the boiling point of liquids, which can be critical in chemical analysis and quality control. The brass construction provides durability and resistance to corrosion while allowing precise calibration of the temperature scale. The ebullioscope operates by heating a liquid sample and observing the temperature at which vapor bubbles form, helping identify purity or concentration levels. During the 19th century, such instruments were important in both laboratory research and industrial processes, reflecting advancements in analytical chemistry. Instruments from makers like Malligand et Fils are valued by historians of science and collectors interested in antique laboratory apparatus.
