Historical Glass Reagent Bottle with Wire Handle - Scientific Instrument Illustration #3449629 (License: Personal Use)

This black-and-white technical illustration depicts a conical-bottomed glass bottle sealed with a ground-glass stopper secured by a metal wire loop handle. The hatching on the right side suggests liquid contents and provides depth, while the central vertical line indicates symmetry or a cross-section view. Such bottles were standard in 19th- and early 20th-century chemistry and pharmacology for storing volatile or sensitive reagents.
