Fluid Appearance and Basic Parameters
Vacuum diffusion pump oil IOTA 705 is a colorless and transparent oily liquid, and its pure appearance allows users to easily monitor the condition of the oil. In terms of physicochemical indicators, the kinematic viscosity of this oil at 25℃ is controlled between 170 and 175 mm²/s, the refractive index is maintained within the range of 1.5765 to 1.5785, and the relative density is 1.090 to 1.10. Regarding temperature tolerance, its flash point (open cup) reaches or exceeds 243℃, and the freezing point is lower than -14 to -18℃. These strict parameter settings ensure that it maintains good fluidity and safety under different temperatures and working conditions. Vacuum Performance and Stability
IOTA 705 possesses an extremely low saturated vapor pressure of less than 3x10⁻¹⁰ torr, while its ultimate vacuum is less than 1x(10⁻⁹~10⁻¹⁰) torr. In the high-temperature working environment of diffusion pumps, it demonstrates good thermal stability and is not prone to cracking or carbon deposition due to high temperatures. In addition, its good oxidation resistance effectively slows down the aging process of the oil during use, reduces the generation of sludge and acidic substances, thereby protecting the internal structure of the pump and ensuring the long-term cleanliness and stable operation of the vacuum system. Wide Applications in Multiple Fields
Relying on its stable performance, IOTA 705 plays an important role in various industrial and scientific research fields. In the high-vacuum smelting industry, it provides a pure environment for metal purification. In the electron tube industry and light bulb manufacturing, it helps maintain a high-vacuum state inside, extending the service life of the products. Meanwhile, in high-vacuum coating processes, it ensures the uniformity and purity of film deposition. In precision instruments, whether it is atomic energy accelerators, electron microscopes, or various high-end display equipment, IOTA 705 serves as a core working medium, providing a solid fluid guarantee for the stable operation of these complex systems.
