Volumetric flask

Object Details

Corning Incorporated

Description (Brief)

This object is a 50 mL volumetric flask made from Pyrex glass. Volumetric flasks are calibrated with great accuracy, for the purpose of preparing dilutions and solutions of a precise volume.

Pyrex has its origins in the early 1910s, when American glass company Corning Glass Works began looking for new products to feature its borosilicate glass, Nonex. At the suggestion of Bessie Littleton, a Corning scientist’s wife, the company began investigating Nonex for bakeware. After removing lead from Nonex to make the glass safe for cooking, they named the new formula “Pyrex”—“Py” for the pie plate, the first Pyrex product. In 1916 Pyrex found another market in the laboratory. It quickly became a favorite brand in the scientific community for its strength against chemicals, thermal shock, and mechanical stress.

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.
