Forscher füllten Glasröhren mit Milzbrandimpfstoff für den Versand am Institut Pasteur im späten neunzehnten Jahrhundert - Stock-Grafiken

This detailed black-and-white engraving, titled "Expédition du vaccin charbonneux : le remplissage des tubes," provides a focused look at the industrial-scale production of life-saving medicine in 1890. The scene depicts two young scientists in white laboratory smocks working methodically at a long wooden bench to prepare doses of the anthrax vaccine developed by Louis Pasteur. On the right, a technician uses a long, delicate glass pipette to transfer the fluid from a large round-bottomed flask into individual glass ampoules, while his colleague on the left manages the supply of empty tubes. Small, steady gas flames from Bunsen burners are positioned on the table, used for aseptic flame sterilization to ensure the purity of the vaccine before the tubes are hermetically sealed for travel. Rendered with fine cross-hatching, the illustration documents the transition of microbiology from experimental research to a globally distributed medical service during the Belle Époque.
