If you need to create a high vacuum, there are basically two options: turbomolecular pumps and diffusion pumps. Turbomolecular pumps require rotors spinning at many thousands of rotations per minute ...

Diffusion and vapor vacuum pumps are devices designed to create high vacuum environments by removing gas molecules from a sealed volume. They achieve this by using high-speed jets of vapor to sweep ...

Dow704 diffusion pump oil (tetramethyl tetraphenyl trisiloxane) is used in large and medium diffusion pumps for a wide range of research and production applications, as the lower attainable pressure ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. Vapor diffusion pumps developed from ...

For a wide range of research and production applications, Dow704 Diffusion Pump Oil (Tetramethyl tetraphenyl trisiloxane) is used in large and medium diffusion pumps since a lower attainable pressure ...

REPORTING recently on the vacuums produced by diffusion pumps, Ray and Sengupta 1 quote my statement "that the limit of pumping is set at the vapour pressure of the pump fluid at room temperature" and ...

HVH Industrial Solutions has become an authorized distributor of DVP Vacuum Technology in the United States. Through this ...

The Agilent AX-65 Oil diffusion pump is the smallest diffusion pump available in the market and the only pump that is air-cooled. Its vertical finned boiler and high power provide stable pumping and ...

THERE has long been a need for a diffusion pump oil which, while hot, would withstand atmospheric pressure without bad effects. G. P. Brown (Rev, Sci. Inst., 16, 316 ; Nov. 1945) has found that ...
