Introduction: The Quest for Perfect Vacuum Conditions

In industries where ultra-high vacuum (UHV) environments are critical—such as electronics, optics, and metallurgy—achieving flawless conditions demands cutting-edge materials. Enter IOTA 705 Silicone Diffusion Pump Oil, a single-component, colorless, transparent fluid engineered to deliver unparalleled performance in vacuum applications ranging from 5x10⁻⁹ to 10⁻¹⁰ torr (untrapped). With its exceptionally low vapor pressure and robust radiation resistance, IOTA 705 isn’t just another lubricant—it’s a cornerstone of modern vacuum technology.

Chemical Mastery: A Formula Built for Excellence

At the heart of IOTA 705 lies its pentaphenyl trimethyl trisiloxane composition, a phenylmethylsiloxane oligomer that ensures superior thermal stability and chemical inertness. This unique structure grants the oil:

• Ultra-Low Vapor Pressure: An extrapolated vapor pressure of 3x10⁻¹⁰ torr at 25°C (77°F), ideal for UHV applications.
• Exceptional Viscosity Control: A viscosity range of 170–175 cSt at 25°C and 61–64 cSt at 40°C, ensuring smooth pump operation across temperature fluctuations.
• Radiation Resistance: Unlike conventional oils, IOTA 705 withstands prolonged exposure to radiation without degradation, a critical trait for nuclear and space research.

Technical Prowess: Numbers That Speak Volumes

IOTA 705’s technical specifications are a testament to its precision engineering:

• Ultimate Vacuum: 1x10⁻⁹ to 10⁻¹⁰ torr (untrapped), setting the standard for UHV applications.
• Flash Point: ≥243°C, ensuring safety in high-temperature processes.
• Refractive Index: 1.5765–1.5785 at 25°C, critical for optical applications.
• Congealing Point: ≤–14°C to –18°C, guaranteeing fluidity even in cold environments.

These metrics translate to longer pump lifespans, reduced maintenance, and consistent performance in demanding settings.
