Introduction to IOTA 705: A Revolution in Vacuum Technology

In the realm of ultra-high vacuum (UHV) applications, precision and reliability are non-negotiable. Enter IOTA 705 Silicone Diffusion Pump Oil, a single-component, colorless, transparent fluid engineered to redefine the standards of vacuum efficiency. With a CAS No. of 3390-61-2 and a chemical structure rooted in pentaphenyl trimethyl trisiloxane, IOTA 705 stands as a beacon of innovation for industries demanding flawless vacuum environments. Whether in laboratories, manufacturing facilities, or research hubs, this oil’s exceptional properties make it indispensable for industries demanding flawless vacuum performance.

Unmatched Technical Specifications for Unparalleled Performance

IOTA 705 is not just another diffusion pump fluid—it’s a technological marvel. Boasting an ultimate vacuum range of 1x(10⁻⁹~10⁻¹⁰) torr (untrapped), this oil is tailored for industries where even trace impurities or pressure fluctuations are unacceptable. Its extrapolated vapor pressure at 25°C (77°F) is an astonishing 3x10⁻¹⁰ torr at 25°C (77°F), making it ideal for applications demanding pristine vacuum environments.
