In the vast realm of high - vacuum technology, IOTA 704 high - vacuum diffusion pump oil shines like a bright star, playing a crucial role in numerous industries with its unique properties.

Basic Information and Appearance

IOTA 704 high - vacuum diffusion pump oil has a specific molecular formula, which serves as the internal foundation for its performance, although it is not detailed here. In terms of appearance, it presents as a colorless or transparent liquid. This pure appearance not only gives an impression of high quality but also holds great significance in practical applications. In high - precision and high - purity high - vacuum environments, its colorless and transparent nature avoids interference caused by impurities, ensuring the stable operation of the entire vacuum system.

Key Technical Specifications

The technical specifications of this oil are remarkable. At 25℃, its viscosity is 38±3 cst. An appropriate viscosity allows it to circulate smoothly in the diffusion pump, neither affecting the pump's operating efficiency due to excessive viscosity nor failing to form an effective oil film due to low viscosity. The refractive index at 25℃ ranges from 1.5500 to 1.5600, and the relative density at 25℃ is between 1.06 and 1.07. These indicators reflect the physical properties of the oil and are of great reference value for precisely controlling the vacuum environment. The flash point (open - cup) is ≥210℃, and a high flash point ensures the safety of the oil under high - temperature working conditions, reducing the risk of fire. The freezing point is -35℃, enabling it to maintain good fluidity in low - temperature environments. The vacuum degree is less than 10 - 7 ~ 10 - 8 Pa, and the saturated vapor pressure is less than 2x10 - 8 Pa. Such low values indicate that it can work effectively in high - vacuum environments and reduce the impact of vapor on the vacuum degree.

Performance and Wide Applications

IOTA 704 high - vacuum diffusion pump oil has a low saturated vapor pressure, good thermal stability, and good oxidation resistance. These performance advantages make it an ideal choice for multiple industries. In the high - vacuum smelting industry, it helps create a stable high - vacuum environment, promoting the refining and purification of metals. In the electron tube industry, it provides reliable vacuum protection for the manufacture of electron tubes. In the light - bulb manufacturing industry, it ensures a high - vacuum state inside the bulbs, extending their service life. In the field of high - vacuum coatings (films), it assists in forming uniform and high - quality coatings. It also plays an indispensable role in atomic energy accelerators, electron microscopes, and displays, providing support for the normal operation of these precision equipment.
