Florence flask

Description (Brief)
This object is a 250 mL Florence flask made from Nonsol glass by Whitall Tatum Company. The Florence flask is characterized by a long neck and rounded bottom with a flat base. It is useful as a reaction vessel as well as for heating solutions.
Nonsol was a brand of borosilicate glass developed by the Whitall Tatum Company. German scientists Otto Schott (1851–1935) and Ernst Abbe (1840–1905) first developed borosilicate glass in the late 19th century. Its strength against chemical attack and low coefficient of thermal expansion made the glass more resistant to the chemical and heat stresses of the laboratory environment than any other glass on the market. When it first became available in 1902, Nonsol was among the first American-made borosilicate glasses. The name “Nonsol” likely was a shortening of “non-soluble,” referring to its chemical resistance.
Whitall Tatum Company was among the first American glass companies to manufacture chemical glassware, starting as early as the late 1870s. Based in Millville, New Jersey, the company’s factory produced chemical and other glassware for over 150 years, finally closing its doors in 1999.
This object is part of a collection donated by Barbara Keppel, wife of C. Robert Keppel. Robert Keppel taught at the University of Nebraska-Omaha after receiving his B.S. in Chemistry from the University of California, Berkeley, and his Ph.D. in organic chemistry from M.I.T. The glassware in the Keppel collection covers the 19th and early 20th centuries.
