IOTA 705 Vacuum Diffusion Pump Oil: A New Experience in High - Vacuum Fields

In numerous industrial fields, a high - vacuum environment is crucial for the realization of many precision processes. IOTA 705 vacuum diffusion pump oil acts as a reliable partner, providing solid support for high - vacuum applications.

Appearance and Basic Characteristics
IOTA 705 vacuum diffusion pump oil appears as a colorless and transparent liquid. This pure appearance not only gives a pleasant visual impression but also implies its high - quality nature. At 25℃, its viscosity ranges from 170 to 175 mm²/s. This appropriate viscosity ensures smooth circulation within the pump, guaranteeing the normal operation of the pump. Its refractive index at 25℃ is between 1.5765 and 1.5785, and its relative density (at 25℃) is in the range of 1.090 to 1.10. These physical properties jointly shape its unique performance.

Excellent Performance
This pump oil has an extremely low saturated vapor pressure, less than 3x10⁻¹⁰ torr. This means that in a vacuum environment, it generates very few vapor molecules, effectively maintaining a high - vacuum state. At the same time, its ultimate vacuum is less than 1x(10⁻⁹ - 10⁻¹⁰) torr, providing reliable protection for high - vacuum processes. Its flash point (open - cup) is ≥243℃, and its freezing point is ≤ - 14 to - 18℃. Its good thermal stability and low - temperature resistance enable it to operate stably under different working temperature conditions. In addition, it has good oxidation resistance, which extends its service life, reduces the replacement frequency, and lowers the use cost.

Wide Range of Applications
IOTA 705 vacuum diffusion pump oil plays an important role in the high - vacuum smelting industry, helping to smelt high - quality metal materials. In the electron tube industry, light bulb manufacturing, and high - vacuum coating (film) fields, it can ensure the quality and performance of products. In areas such as atomic energy accelerators, electron microscopes, and displays, it also provides strong support for the stable operation of equipment, promoting technological development in these fields.
