In the world of precision manufacturing and high-end scientific research, a high-vacuum environment is a core prerequisite for achieving superior quality. From the engraving of electronic chips to the precise deposition of optical coatings, from the operation of atomic accelerators to the microscopic exploration of electron microscopes, every step relies on a stable and reliable vacuum system. Behind this, high-vacuum diffusion pump oil is the indispensable "invisible cornerstone." IOTA-704, as a benchmark product in this field, safeguards the high-vacuum needs of various industries with its ultimate performance.
High vacuum systems place stringent requirements on pump oil performance, with saturated vapor pressure, thermal stability, and oxidation resistance being the three core indicators. Ordinary oils are prone to volatile emissions in a vacuum environment, and the resulting oil vapor can contaminate the cavity, compromise vacuum levels, and even cause workpiece failure. Furthermore, under high-temperature conditions, substandard oils can decompose and coke, clogging equipment pipelines and significantly shortening equipment lifespan. IOTA-704 was developed precisely to address these industry pain points.
As a colorless and transparent oily liquid, IOTA-704 possesses an extremely low saturated vapor pressure, as low as 5 × 10⁻⁸ torr at room temperature. Combined with its excellent fractionation purification characteristics, it helps systems easily achieve ultimate vacuum levels of 10⁻⁷ to 10⁻⁸ torr. This characteristic means it is virtually non-volatile in a vacuum environment, effectively preventing oil vapor contamination of workpieces and equipment, and providing clean vacuum conditions for high-end manufacturing. Whether it's the etching and deposition of semiconductor wafers or the precision manufacturing of electron tubes, this purity enables quality upgrades.
Facing the high-temperature conditions of industrial production, IOTA-704 also demonstrates outstanding thermal stability and oxidation resistance. With a flash point as high as 210℃ and a freezing point as low as -35℃, it maintains chemical stability within storage temperatures ranging from -40℃ to 50℃ and in high-temperature operating environments, resisting decomposition to produce tar and carbon deposits, thus ensuring unobstructed pump nozzle flow. Even with brief exposure to air at high temperatures, it effectively resists oxidative deterioration, preventing the formation of gum and sludge, significantly extending oil change intervals and equipment lifespan, and reducing maintenance costs for businesses.
With its balanced performance advantages, IOTA-704 has applications covering multiple high-end fields. In the high-vacuum smelting industry, it can provide a stable vacuum environment for the purification of metal materials, improving material purity and mechanical properties. In the field of vacuum coating, whether it is an anti-reflective coating for optical lenses, a heat insulation film for automotive glass, or a functional coating for semiconductor devices, it can ensure uniform deposition of coating particles, improving film adhesion and optical performance.
In scientific research and electronics, IOTA-704 also performs exceptionally well. Atomic accelerators require an extreme vacuum environment to operate, and its stable performance ensures undisturbed particle motion. Electron microscopes rely on ultra-high vacuum for microscopic observation, and its extremely low volatility prevents sample contamination, helping researchers capture precise images. Furthermore, in the manufacture of products such as electron tubes, light bulbs, and displays, its stable vacuum ensures improved product performance and lifespan.
