Test Tube
notes: label: Description
content: Glass test tube with a paper label that reads "Vycor / 13 mm / Keppel." Vycor is the brand name of Corning's high-silica, high-temperature glass. It was invented in 1939 and unveiled at a New York fair in 1940. Vycor, which provides very high thermal shock resistance, is approximately 96% silica and 4% boron trioxide, but unlike pure fused silica, it can be readily manufactured in a variety of shapes.
