Redefining High-Vacuum Efficiency and Durability

For industries reliant on high-vacuum processes, the choice of diffusion pump oil can make or break operational success. IOTA704 Silicone Diffusion Pump Oil is engineered to tackle the toughest challenges, delivering ultra-low pressures, rapid recovery, and long-term stability. Backed by decades of research, this oil is a trusted companion for applications spanning electronics, metallurgy, optics, and beyond.

Superior Chemistry, Superior Results
IOTA704’s molecular structure—tetramethyl tetraphenyl trisiloxane—is optimized for high-vacuum performance. Key advantages include:

• Ultra-High Vacuum Capability: Achieves 10⁻⁷ to 10⁻⁸ torr untrapped, critical for processes like sputtering, evaporation, and thin-film deposition.
• Low Vapor Pressure: Minimizes oil migration into vacuum chambers, preserving sample integrity and reducing contamination risks.
• Wide Temperature Range: From -35°C to ≥210°C, it maintains fluidity without degradation, even in thermally demanding environments.

Applications That Demand the Best

• Optical Manufacturing: Ideal for anti-reflective coatings, optical filters, and laser mirrors, where surface perfection is paramount.
• Electronic Device Production: Ensures flawless vacuum sealing in TV tubes, capacitors, and rectifier systems.
• Metallurgical Processes: Supports high-vacuum furnaces, degassing, and melting of refractory metals with zero contamination.
• Advanced Research: Powers mass spectrometers, particle accelerators, and molecular beam epitaxy systems.
