Specific Gravity Bottle

Specific Gravity Bottle

Usage conditions apply
This specific gravity bottle is based on the design of Henri Le Chatelier, an industrial chemist in Paris with a stated desire to apply scientific methods to industrial problems. His 1887 doctoral dissertation concerned the constitution of hydraulic cements. The “A.H.T.” inscription on the bottle is that of Arthur H. Thomas, an important scientific apparatus firm in Philadelphia.
By 1921, Arhur H. Thomas was offering a “Specific Gravity Bottle, Le Chatelier, New Form, in accordance with the U.S. Bureau of Standards requirements, and as used in the U.S. Government test for Portland cement.”
