    Spiral borosilicate glass tube manometer

    This glass instrument was made for Joseph Ritter, a National Bureau of Standards researcher in the Inorganic Materials Division, circa 1966. It was donated to the collection by Jeff Anderson, a glassblower at the National Institute of Standards and Technology as a particularly impressive example of the work of his predecessor, Enrico (Hank) DeLeonibus. According to Ritter, the instrument is a spiral borosilicate glass tube manometer. Ritter used it in a preparative chemical vacuum system. These vacuum systems were used to manipulate water and oxygen sensitive gases. Typically, in the 1960’s, preparative chemical vacuum systems were equipped with mercury manometers for pressure measurement allowing for subsequent quantitation of reactants and products using the ideal gas law equation. Unfortunately, mercury vapor also reacted with some of the more sensitive compounds with which Ritter was working at that time. In 1966, Ritter solved the problem by going mercury-free with a pair of these spiral glass tube manometers installed in the volume-calibrated portions of his systems. Essentially, this instrument consist of an inner chamber with a hollow glass tube that is attached to a hollow glass spiral, the end of which is connected to a small mirror. An outer chamber encloses the spiral and mirror assembly and its lower end is equipped with a flat optical window in the region where the mirror resides. The two chambers are sealed and thus isolated from each other. In use, both chambers were evacuated to a pressure of about 10 -6 torr. When a small amount of gas was introduced into the inner chamber, the glass spiral would unwind and cause the mirror to rotate. This rotation was detected using a narrow light beam passing through the optical window, reflecting off of the mirror and back out to illuminate a graduated frosted glass screen. The graduations on the screen were calibrated to represent the gas pressure in torr. (In those times, the preferred pressure units commonly used were torr; where 1 torr = 1mm/Hg.) As with the mercury manometer, the operational pressure range for the spiral tube manometers was from about 1 to 760 torr (1 atmosphere).[H] 27 cm [Diam] 5 cmA24/29
