A Leap Forward in Vacuum Fluid Technology

In the quest for perfection, Silicone Diffusion Pump Oil IOTA 705 emerges as a game-changer. Designed for ultra-high vacuum (UHV) environments, this phenylmethylsiloxane oligomer redefines what’s possible. With a CAS No. 3390-61-2 and a molecular weight of 546, it’s a testament to precision engineering. From electronics to metallurgy, IOTA 705 is the silent hero behind countless innovations.

Unrivaled Performance Metrics

IOTA 705’s technical specifications are a masterclass in efficiency:

• Ultimate Vacuum: Achieves 1x(10⁻⁹~10⁻¹⁰) torr (untrapped), ideal for semiconductor fabrication and particle accelerators.
• Vapor Pressure: At 3x10⁻¹⁰ torr (25°C), it minimizes outgassing, a critical factor in space-grade components.
• Viscosity & Flow: A 170~175 cSt rating at 25°C ensures smooth pump operation, while 61~64 cSt at 40°C adapts to varying temperatures.
• Safety & Durability: A flash point ≥243°C and refractive index of 1.5765~1.5785 guarantee reliability in high-stakes environments.
