Description (Brief)
This glass pipette, from the University of Michigan Medical School Hygienic Laboratory, was used to transfer small quantities of liquids from one vessel to another in bacteriological investigations. The pipettes were used like straws—the liquid to be transferred was drawn up through mouth suction and the tongue or finger used to close off the tube while the material was moved to another test tube or flask.
The Michigan laboratory was established in 1887 under the direction of Dr. Victor Vaughan (1851–1929), Professor of Hygiene and Physiological Chemistry and his assistant Frederick Novy (1864–1957). The laboratory was one of the first in the country to offer courses in the relatively new science of bacteriology. Vaughan and Novy traveled to Europe to learn bacteriological techniques at Robert Koch’s laboratory in Berlin and also visited Pasteur’s laboratory in Paris. Equipment for the new laboratory was purchased during this trip. Novy credits the Pasteur school for developing the methods for preparing and using the glass pipettes. He describes these techniques for his students in his laboratory manual published in 1899.
The pipettes were made from lengths of standard glass tubing of about fourteen inches. The tubes were heated in the middle over a blast-lamp until soft and the two ends slowly drawn apart to form a long thin capillary. This was then heated again at the center to completely seal and divide the tube thus forming two pipettes. The pipettes were then sterilized and cotton plugs inserted in the open end to prevent further contamination. Thus prepared, a quantity of pipettes could be kept on hand until needed during investigations.
