In the realm of high-vacuum technologies, finding the right diffusion pump oil is crucial for achieving optimal performance. One standout product in this field is Silicone Diffusion Pump Oil IOTA 705, a colorless, transparent, and single-component fluid designed specifically for ultrahigh vacuum applications.

Silicone Diffusion Pump Oil IOTA 705

This remarkable oil boasts an ultimate vacuum range of 5x(10-9~10-10) torr (untrapped), making it an ideal choice for applications where extremely low pressures are required. One of its key attributes is its extraordinarily low vapor pressure, with an extrapolated value of 3x10-10 at 25°C (77°F). This ensures minimal evaporation, even in the most demanding vacuum environments. Additionally, IOTA 705 exhibits excellent resistance to radiation, which is essential for applications where the oil may be exposed to radioactive materials or processes.

The technical index of IOTA 705 further underscores its superiority. With a specific gravity of 1.090 to 1.100 and a viscosity range of 170-175 cSt at 25°C, it offers the perfect balance of flow characteristics and thermal stability. Its high flash point of ≥243°C ensures safety during operation, while its refractive index and congealing point make it suitable for a wide range of temperatures. These properties, combined with its molecular description of 546, make IOTA 705 a versatile and reliable choice for numerous high-vacuum applications.

Versatile Applications Across Industries

The applications of Diffusion Pump Fluid IOTA 705 are vast and diverse. In the electrical and electronics industry, it is used in the production of TV tubes, fluorescent tubes, cathode ray tubes, and ordinary bulbs. It also plays a crucial role in the manufacturing of capacitors and rectifier metallised film vacuum systems. The optical industry benefits from its use in surface improvements, anti-reflective coatings, optical filters, and mirrors. In the metallurgy industry, IOTA 705 is employed in high-vacuum furnaces for melting, degassing, and sintering refractory metals, as well as for thick-film deposition. The plastics industry utilizes it for surface improvements, mirror coatings, protective coatings, and film coatings. Furthermore, it is used in processing metals and fuels, accelerators, molecular plants, R&D plants, and mass spectrometry, among others. Its versatility even extends to being used as a transmission fluid in high-temperature carriers and various instruments.
