In the realm of high - vacuum applications, having a high - quality diffusion pump oil is of utmost importance, and High - Vacuum Diffusion Pump Oil IOTA 704 stands out as a trustworthy option. It presents itself as a colorless or transparent liquid, giving an immediate impression of purity and professionalism.

When it comes to technical specifications, IOTA 704 excels. At 25℃, its viscosity is precisely controlled at 38±3cst. This appropriate viscosity range ensures smooth flow within the pump oil circulation system, providing effective lubrication and sealing for the pump's normal operation. The refractive index at 25℃ lies between 1.5500 and 1.5600, and the relative density at the same temperature is in the range of 1.06 - 1.07. These parameters reflect its unique physical properties. With a flash point (open - cup) of no less than 210℃ and a freezing point of - 35℃, it can operate stably across a wide temperature range, whether in high - temperature or low - temperature environments, without significant performance degradation. The vacuum degree is less than 10 - 7~10 - 8Pa, and the saturated vapor pressure is less than 2x10 - 8Pa. Such low values indicate its extremely low volatility, enabling it to effectively reduce the interference of vapor on the vacuum degree in high - vacuum environments and maintain a stable high - vacuum state.

Performance and Applications: Versatile and Effective

In terms of performance, IOTA 704 is truly remarkable. It has a very low saturated vapor pressure resistance, good thermal stability, and good oxidation resistance. These characteristics make it an ideal choice in various industries. In the high - vacuum smelting industry, it can create a stable high - vacuum environment for the smelting process, ensuring the quality of smelted products. In the electron tube industry and light bulb manufacturing, it helps improve product performance and extend service life. In the field of high - vacuum coatings (films), it guarantees the uniformity and quality of the coatings. It also plays a crucial role in atomic energy accelerators, electron microscopes, and displays, providing reliable support for the normal operation of these precision equipment.

Packaging and Storage: Ensuring Product Quality

IOTA 704 offers multiple packaging options to meet different customer needs. It comes in 1 - kilogram plastic bottles, 5 - kilogram, 25 - kilogram, and 50 - kilogram plastic drums, as well as 200 - kilogram iron drums. The finished products are stored and transported in warehouses that are moisture - proof, humidity - proof, and away from direct sunlight, with an allowable indoor temperature range of - 40～50℃. This storage condition effectively protects the quality of the pump oil. Moreover, it is transported and stored as non - dangerous goods, making the transportation process more convenient and safe. With a shelf life of 3 years, customers can use it with confidence. The brand IOTA is also known for its professional research and development and production teams, providing a solid guarantee for product quality.
