ArChine Diffutech 705
Vacuum Diffusion Pump Oil
Production Description:
Equivalent Brand: DOW Corning 705, MT-705, HIVAC-F-5
ArChine Diffutech 705 oil is a colorless to light yellow transparent oily, single-component fluid designed for ultrahigh vacuum applications in the range of 5 x (10-9~10-10) torr (untrapped). The vapor pressure and backstreaming rate of 705 oil is so low that the use 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 oils and the best resistance to radiation.
