Introduction: The Pinnacle of Vacuum Technology

In the realm of ultra-high vacuum (UHV) systems, precision and reliability are non-negotiable. Enter Silicone Diffusion Pump Oil IOTA 705, a revolutionary fluid engineered to redefine performance standards. With a CAS No. of 3390-61-2 and a chemical structure rooted in 1,1,3,5,5-Pentaphenyl-1,3,5-trimethylsiloxane, this single-component oil stands as a cornerstone for industries demanding flawless vacuum environments. Whether it’s safeguarding delicate electronics or enabling cutting-edge metallurgical processes, IOTA 705 delivers unmatched efficiency.

Technical Mastery: Where Science Meets Excellence

IOTA 705’s technical prowess is unparalleled. Boasting an ultimate vacuum range of 1x(10⁻⁹~10⁻¹⁰) torr (untrapped), it outperforms conventional oils, ensuring minimal backstreaming and contamination. Its extrapolated vapor pressure at 25°C (77°F) of 3x10⁻¹⁰ torr guarantees stability under extreme conditions, while a specific gravity of 1.090~1.100 and viscosity range of 170~175 cSt at 25°C optimize pump efficiency. With a flash point ≥243°C and congealing point ≤-14~-18°C, it thrives in diverse climates.
