In numerous industrial production and scientific research scenarios, the construction of a high vacuum environment is a fundamental prerequisite for many precision processes to proceed smoothly. As the core working medium during the operation of diffusion pumps, the performance of diffusion pump oil directly affects the operating status and output quality of the entire vacuum system. IOTA 704 High Vacuum Diffusion Pump Oil is a special oil developed for these high-demand scenarios. With stable parameter performance, it has been widely applied in multiple industries.

Clear and Standardized Core Technical Specifications

IOTA 704 appears as a colorless or transparent liquid, without excess impurities or turbidity. After being injected into the pump body, the oil level can be observed clearly, allowing operators to check the oil status at any time. Under the standard environment of 25℃, its kinematic viscosity is 38±3 cst. This viscosity range enables the oil to form a stable jet flow inside the pump body. It will not cause excessive operation resistance of the pump due to high viscosity, nor will it lead to oil backflow due to low viscosity. Its refractive index at 25℃ ranges from 1.5500 to 1.5600, and its relative density at the same temperature is 1.06 to 1.07. These stable physical properties prevent the oil from stratifying or precipitating during long-term storage, and allow relevant personnel to verify the oil quality quickly through conventional testing methods. Its open-cup flash point is no less than 210℃. Within the conventional operating temperature range of equipment, it is not easy to cause fire risks, providing more guarantees for the safety management of workshop production. Its freezing point is -35℃. Even when stored or operated in a low-temperature environment, it can maintain a normal flow state without the problem of oil solidification blocking the pump pipeline. 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. Such performance can meet the basic needs of most high-vacuum scenarios.

Practical Performance Adapted to Diverse Scenarios

As a colorless and transparent oily liquid, IOTA 704 has a low saturated vapor pressure, along with good thermal stability and oxidation resistance. In the high-vacuum smelting industry, it helps the equipment quickly build a vacuum environment that meets the requirements, reducing the mixing of impurities during the smelting process and improving the smelting quality of metal materials. In the electronic tube and bulb manufacturing industry, a stable vacuum environment can prevent components such as filaments from being oxidized at high temperatures, extending the service life of products. In the high-vacuum coating process, it can maintain a stable vacuum state for a long time, allowing the coating material to evenly adhere to the surface of the workpiece and improving the uniformity and adhesion of the coating. In addition, it can also be adapted to the supporting vacuum systems of atomic energy accelerators, electron microscopes, displays and other equipment, providing support for the stable operation of these precision instruments.
