Manufactured according to BS.1922 in heavy walled borosilicate glass with permanent. National Museum of American History Accession File #1985.0311 Beaker measures developed for intensive dispensing use. In order to do this, we can subtract the weight of the 100mL beaker from the weight of the 100 mL beaker with 10mL in order to get just the weight of the 10 mL of water. These 100ml Borosillicate glass beakers are useful additions to your brewery, use during brewing to measure additions or during distilling to measure your cuts. “A History of the Chemical Apparatus Industry.” Journal of Chemical Education 10, no. 100 mL beaker weighs 5.246g 100mL beaker with 10mL weighs 15.346g And we want to find how much does the 10mL of water weigh alone. “The Origin of Pyrex.” Journal of Chemical Education 83, no. Oxford, New York: Oxford University Press, 2001. The Generations of Corning: The Life and Times of a Global Corporation. The glassware in the Keppel collection covers the 19th and early 20th centuries.ĭyer, Davis. in Chemistry from the University of California, Berkeley, and his Ph.D. Robert Keppel taught at the University of Nebraska-Omaha after receiving his B.S. This object is part of a collection donated by Barbara Keppel, wife of C. It quickly became a favorite brand in the scientific community for its strength against chemicals, thermal shock, and mechanical stress. In 1916 Pyrex found another market in the laboratory. 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. Borosilicate glass beaker is suitable for measuring and storing liquids within a laboratory, household or baking. At the suggestion of Bessie Littleton, a Corning scientist’s wife, the company began investigating Nonex for bakeware. This 100ml capacity thermal resistant 3.3. 5ml raised graduations and specifications. 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. Pack of 10, 100ml beakers made of premium quality, translucent polypropylene plastic. ![]() His interest in bringing chemistry to the common man led him to publish popular works on the subject and eventually to begin supplying scientific apparatus, including his eponymous beakers. The Griffin beaker’s name refers to John Joseph Griffin (1802–1877), an English chemistry enthusiast. Short, squat beakers are referred to as Griffin beakers, differentiating them from taller, thinner beakers known as Berzelius beakers. This is a 30 mL Griffin beaker made of Pyrex glass.
