In the world of high - vacuum technology, every detail matters. High - vacuum diffusion pump oil IOTA 704 stands out as a premium choice for numerous high - vacuum applications, thanks to its exceptional quality and stable performance.

Appearance and Physical Characteristics

The colorless or transparent appearance of IOTA 704 gives a sense of freshness and purity. At 25℃, its viscosity of 38±3cst provides an appropriate level of fluidity during the pumping process, minimizing energy loss. With a refractive index between 1.5500 - 1.5600 and a relative density of 1.06 - 1.07 at 25℃, it offers certain advantages in optical and density - related applications.

Safety and Performance Parameters

The flash point (open cup) of ≥210℃ ensures the safe operation of equipment, even in high - temperature conditions, effectively preventing potential fire hazards. Its freezing point of -35℃ allows it to function normally in cold regions or low - temperature working environments, broadening its applicability. The vacuum degree of ＜10⁻⁷ - 10⁻⁸Pa and the saturated vapor pressure of ＜2×10⁻⁸Pa make it well - suited for the stringent requirements of high - vacuum equipment.

Versatile Application Scenarios

In the high - vacuum smelting industry, IOTA 704 creates a pure environment for metal smelting, enhancing the quality and performance of the metals. In the electron tube industry, it contributes to the stable operation of electron tubes, ensuring the normal functioning of electronic devices. In bulb manufacturing, it improves the brightness and stability of bulbs, extending their service life. In the high - vacuum coating (film) field, it supports the uniformity and adhesion of coatings, resulting in more aesthetically pleasing and durable coatings. In areas such as atomic energy accelerators, electron microscopes, and displays, it also plays a crucial role in enhancing the performance of these high - precision devices.
