DC 705

Dow Corning 705 Diffusion Pump Fluid

Dow Corning 705® is a colourless to straw-coloured, single-component fluid designed for ultra-high vacuum applications in the range of 10-9 to 10-10 torr (untrapped) and 10-11 torr (trapped). The vapour pressure and backstreaming rate of Dow Corning 705 Diffusion Pump Fluid are so low that use of traps or refrigeration is unnecessary for some ultra-high and ultra-clean vacuum applications. It has the highest phenyl content of all silicone diffusion pump fluids and the best resistance to radiation.
