In the realm of advanced engineering and scientific research, achieving ultra-high vacuum (UHV) environments is not merely a challenge—it is a necessity. Enter Silicone Diffusion Pump Oil IOTA 705, a revolutionary fluid engineered to redefine the boundaries of vacuum technology. With its exceptional chemical stability, low vapor pressure, and unparalleled resistance to radiation, IOTA 705 stands as a beacon of reliability in industries where precision is non-negotiable.

A Symphony of Purity and Performance

IOTA 705 is not just another diffusion pump oil; it is a meticulously crafted single-component fluid designed for applications demanding the utmost purity. Its chemical composition, Pentaphenyl trimethyl trisiloxane, ensures a molecular structure that minimizes outgassing and contamination, making it ideal for UHV systems operating in the range of 5×10⁻⁹ to 10⁻¹⁰ torr (untrapped). This performance is underscored by its extrapolated vapor pressure of 3×10⁻¹⁰ torr at 25°C (77°F), a benchmark that sets it apart in industries where even trace impurities can compromise results.

But IOTA 705’s brilliance extends beyond its chemical purity. Its specific gravity of 1.090–1.100 and viscosity range of 170–175 cSt at 25°C (61–64 cSt at 40°C) provide a perfect balance of fluidity and thermal stability, ensuring consistent performance across a wide temperature spectrum. With a flash point of ≥243°C, it offers enhanced safety in high-temperature applications, while its congealing point of ≤–14 to –18°C guarantees low-temperature flexibility without sacrificing viscosity.

Versatility Across Industries

The true power of IOTA 705 lies in its adaptability. In the electrical and electronics industry, it is the backbone of vacuum systems for TV tubes, fluorescent tubes, cathode ray tubes, ordinary bulbs, capacitors, and rectifier metallised film systems, ensuring flawless operation and longevity. The optical industry leverages its properties for surface improvements, anti-reflective coatings, optical filters, and mirrors, where even microscopic imperfections can degrade performance.

In metallurgy, IOTA 705 enables high-vacuum furnaces for melting, degassing, and sintering refractory metals, as well as thick-film deposition processes that demand pristine environments. The plastics industry benefits from its role in surface improvements, mirror coatings, protective coatings, and film coatings, enhancing product durability and aesthetics.

Beyond these, IOTA 705 finds applications in metal and fuel processing, accelerators, molecular plants, R&D facilities, and mass spectrometry, where its ability to maintain UHV conditions is indispensable. It even serves as a transmission fluid in high-temperature carriers and various instruments, proving its versatility in niche yet critical applications.
