Silicone Diffusion Pump Oil IOTA 705, also known as 1,1,3,5,5-Pentaphenyl-1,3,5-trimethylsiloxane or 705 Super high vacuum diffusion pump oil, is a colorless transparent, single-component fluid specifically engineered for ultrahigh vacuum applications. With an ultimate vacuum range of 1x(10-9~10-10) torr (untrapped) and an extrapolated vapor pressure of 3x10-10 at 25°C, IOTA 705 boasts exceptional vapor pressure characteristics and radiation resistance. Its specific gravity, viscosity, flash point, and refractive index make it an ideal choice for demanding vacuum environments.
