Mercury diffusion pump

WebIrving Langmuir invented the diffusion pump, using mercury as the pump fluid. The use of mercury enabled the pump to continue working at elevated temperatures, but was soon replaced due to its toxicity. By the 1920s, the oil-sealed rotary vane mechanism was the typical design for most primary pumps. WebFor vacuums in the range lO" mm Hg to 10 mm Hg, rotary mechanical pumps (oil pumps) are used and the pressure can be measured with a Vacustat McLeod type gauge. If still higher vacuums are required, for example for high vacuum sublimations, a mercury diffusion pump is suitable. Such a pump can provide a vacuum up to 10" mm Hg.
