Specific Gravity Bottle 25 ml

A specific gravity bottle, also known as a pycnometer, with a 25 ml capacity is a precision laboratory glassware used to measure the specific gravity (relative density) of liquids. It is typically made of high-quality glass to ensure accuracy and chemical resistance.

The bottle is designed with a narrow neck and a tightly fitting stopper with a capillary hole that allows excess liquid to escape, ensuring consistent volume measurement. This precise volume control is critical for calculating the specific gravity by comparing the mass of the liquid to that of an equal volume of water. Such bottles are commonly used in chemical, pharmaceutical, and industrial laboratories for density determination.
