The gas in a glovebox is pumped through a series of treatment devices which remove solvents, water and oxygen from the gas. Copper metal (or some other finely divided metal) is commonly used to remove oxygen, this oxygen removing column is normally regenerated by passing a hydrogen/nitrogen mixture through it while it is heated: the water formed is passed out of the box with the excess ...
An ordinary glovebox, showing the two gloves for manipulation, with airlock on the right. The most straightforward type of air-free technique is the use of a glovebox.A "glove bag" uses the same idea, but is usually a poorer substitute because it is more difficult to purge, and less well sealed.
Vacuum, venting, nitrogen gas dilution (that can keep the work volume oxygen volume fraction below the standard ISS atmosphere (nominally 21% by volume) down to 10 percent or less), power and data interfaces are also provided within MSG.
Schlenk bombs are often used to conduct reactions at elevated pressures and temperatures as a closed system. In addition, all Schlenk bombs are designed to withstand the pressure differential created by the ante-chamber when pumping solvents into a glove box. In practice Schlenk bombs can perform many of the functions of a standard Schlenk flask.
This is the second glove box breach in as many months and among a half-dozen the safety board has reported this year. Although this year's breaches have been deemed minor, anti-nuclear activists ...
The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
