In the era of continuous advancement in high - vacuum technology, IOTA 705 vacuum diffusion pump oil has emerged as an indispensable key material in numerous industrial sectors. It shares similarities with foreign brands CF - 5,705 and has the same category as the domestic brand number 275, which serves as a strong endorsement of its quality.
Visually, IOTA 705 is a colorless and transparent liquid. This pure appearance not only gives a high - quality impression but also reduces the impact of impurities on equipment in practical applications. At 25℃, its viscosity ranges from 170 to 175 mm²/s. This appropriate viscosity ensures good fluidity and sealing in the diffusion pump. The refractive index at 25℃ is between 1.5765 and 1.5785, and the relative density (at 25℃) is between 1.090 and 1.10. These indicators collectively reflect its unique physical properties. With a flash point (open - cup) of no less than 243℃, it offers high safety and is less likely to catch fire at high temperatures. The freezing point is no more than - 14 to - 18℃, allowing it to remain in good condition in low - temperature environments. The ultimate vacuum is less than 1x(10 - 9~10 - 10) torr, and the saturated vapor pressure is less than 3x10 - 10 torr. These extremely low values provide a solid foundation for creating a high - vacuum environment.
IOTA 705 has a very low saturated vapor pressure, which means it produces minimal vapor in a vacuum environment and can effectively maintain a high - vacuum state. Its good thermal stability enables it to withstand high - temperature working conditions without decomposition or deterioration, ensuring long - term reliability. The excellent oxidation resistance extends the service life of the oil, reducing the frequency of replacement. It is widely used in high - vacuum metallurgy, the electron tube industry, light bulb manufacturing, high - vacuum coating (film) fields, as well as in atomic energy accelerators, electron microscopes, and displays.
In terms of packaging, IOTA 705 offers multiple options, including 1 - kg plastic bottles, 5 - kg, 25 - kg, and 50 - kg plastic drums, and 200 - kg iron drums, meeting the needs of different users. During storage and transportation, it should be placed in a warehouse that is moisture - proof, humidity - proof, and away from direct sunlight, with an indoor temperature range of - 40 to 50℃. It is transported and stored as a non - toxic and non - dangerous product, which is convenient and safe. With a shelf life of 3 years, users can use it with confidence. The IOTA brand has also established a good reputation in the high - vacuum field with this product.
