Specific Gravity Flask (Chapman)

Chapman Specific Gravity Flask is used to determine the approximate percentage of surface moisture in fine aggregates with known specific gravity values.

Its large bulb body and finely graduated long-neck design allow clear visibility of the meniscus and increase reading accuracy, even with small volume changes. The thick-walled borosilicate glass is resistant to thermal shock and chemical interactions, maintaining dimensional stability.
