IOTA 705: A Legacy of Excellence in Vacuum Engineering

In the world of ultrahigh vacuum (UHV) systems, Silicone Diffusion Pump Oil IOTA 705 has earned its reputation as a benchmark for quality and reliability. With a chemical structure rooted in 1,1,3,5,5-pentaphenyl-1,3,5-trimethylsiloxane, this fluid is engineered to deliver exceptional performance in applications where even the slightest deviation can lead to catastrophic failure.

Technical Superiority: The Numbers Behind the Performance

1. Ultimate Vacuum Capability
   IOTA 705 achieves an ultimate vacuum of 1x(10⁻⁹~10⁻¹⁰) torr (untrapped), making it suitable for the most demanding UHV environments. This capability is critical in semiconductor fabrication, nuclear research, and high-energy physics.

2. Thermal and Chemical Stability

   • Flash Point (≥243°C): Ensures safety during high-temperature operations.
   • Congealing Point (≤–14 to –18°C): Allows use in cryogenic applications without freezing.
   • Refractive Index (1.5765–1.5785): Maintains optical clarity in lens and mirror manufacturing.

3. Viscosity and Flow Characteristics

   • 25°C Viscosity (170–175 cSt): Provides optimal lubrication for pump components.
   • 40°C Viscosity (61–64 cSt): Ensures smooth operation at elevated temperatures.

4. Radiation Resistance
   Unlike conventional oils, IOTA 705 withstands radiation exposure, making it indispensable in nuclear accelerators and medical imaging equipment.
