Lyophilization Flask
notes: label: Description
content: Janet McCarter (1906-1996), a bacteriologist at the University of Wisconsin, worked with Prof. E. G. Hastings on tubercule bacilli for her PhD research, and continued to work in this area for many years. In 1944, then an assistant professor in the Department of Agricultural Bacteriology at Wisconsin, Dr. McCarter was awarded a Guggenheim Fellowship for her work in immunology, especially as applied to tuberculosis. In 1945, McCarter married Dilworth Wayne Woolley, a biochemist, and "played an essential role in his work."
label: Description
content: Dr. McCarter used this glass flask for lyophilization of bacterial cultures in the 1930s. Lyophilization or freeze drying is a process in which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase.
