For technicians who have long been exposed to high-vacuum equipment, choosing a diffusion pump oil with stable properties and strong adaptability is an important link to reduce equipment maintenance frequency and ensure the progress of production and experiments. Starting from the needs of actual usage scenarios, IOTA 704 High Vacuum Diffusion Pump Oil has been specially adjusted in various performances, and can show stable usage effects under different working conditions.

Fully Controlled Physical Property Performance

IOTA 704 is a colorless or transparent liquid without excess odor or impurities. Before being opened for use, the purity of the oil can be initially judged directly through the naked eye. The kinematic viscosity of 38±3 cst at 25℃ has been verified by a large number of actual working conditions. It is compatible with most conventional models of high-vacuum diffusion pumps, and can quickly enter a stable working state without additional adjustment of the heating temperature of the pump body. Its refractive index is stably maintained between 1.5500 and 1.5600, and its relative density is controlled in the range of 1.06 to 1.07. The consistent performance of these parameters allows different batches of oil to maintain similar usage experiences, and there will be no obvious fluctuation of equipment vacuum degree after replacing new oil. Its open-cup flash point is no less than 210℃. During the long-term continuous operation of the equipment, even if the local temperature of the pump body rises slightly, the oil will not easily have problems such as intensified volatilization or deterioration. The performance of the freezing point at -35℃ allows it to be used normally in non-constant temperature workshops in northern winters, or in temporary outdoor experimental scenarios, without preheating the oil in advance. In terms of core vacuum indicators, it can achieve a vacuum degree less than 10^-7 ~ 10^-8 Pa, and its saturated vapor pressure is less than 2×10^-8 Pa, which can still maintain a stable vacuum performance after long-term operation.

Application Value Covering Multiple Industries

IOTA 704 has a low saturated vapor pressure, along with good thermal stability and oxidation resistance. During long-term use, the deterioration speed of the oil is relatively slow, which can appropriately extend the oil change cycle and reduce the operation and maintenance cost of the equipment. In the high-vacuum smelting industry, a stable vacuum environment can reduce the reaction between the molten metal and the components in the air, helping to smelt metal materials with uniform composition. On the production lines of electronic tubes and bulbs, it can quickly pump the pressure in the chamber to the specified range, improving the circulation efficiency of the production line. In the high-vacuum coating process, a stable vacuum state for a long time can keep the thickness of the coating uniform, reducing the probability of defective workpieces. At the same time, it can also be used in the vacuum systems of atomic energy accelerators, electron microscopes, displays and other equipment, providing reliable medium support for the daily operation of these devices, and helping the related scientific research and production work proceed smoothly.
