Modified Claisen flask
- Description (Brief)
- This modified Claisen flask is made of Pyrex glass.
- 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.
