DSS Diffusion Pump Fluid

FOVAC® DSS Diffusion Pump Fluid is a colorless to straw-colored, synthetic silicone oil base single component fluid designed for ultrahigh vacuum applications in the range of 10-9 to 10-10 torr (untrapped) and 10-11 torr (trapped). The vapor pressure and backstreaming rate of FOVAC _® DSS are so low that use of traps or refrigeration is unnecessary for some ultrahigh and ultraclean vacuum applications. It has the highest phenyl content of all silicone diffusion pump fluids and the best resistance to radiation. High spontaneous ignition temperature makes this fluid ideal for use in humanrated space simulation chambers.
