Antique Glass Dropper Pipettes and Vial Set - 5 Pieces

A set of five antique laboratory or apothecary glass pieces, including four glass dropper pipettes and one small glass vial. Two of the pipettes have large, wide metal bulb tops with significant patina and oxidation, suggesting an older style commonly associated with early 20th century scientific or medical use. The other two pipettes have smaller black rubber bulb tops in varying states of deterioration. The central glass vial contains a dried red or crimson powdery residue - the identity of this substance is unknown. Glass tubes are clear and appear intact without visible cracks. Metal fittings on the two wider-topped droppers show heavy tarnish and corrosion. Rubber bulbs on the remaining two are cracked and degraded. Each pipette measures approximately 4 to 5 inches in length. This set would appeal to collectors of antique scientific instruments, apothecary decor enthusiasts, or laboratory curiosity displays.
