n the realm of ultrahigh vacuum technology, precision is everything. Silicone Diffusion Pump Oil IOTA 705 is a state-of-the-art fluid designed to deliver unmatched performance in the most demanding applications. With its low vapor pressure and exceptional resistance to radiation, IOTA 705 is the ultimate solution for achieving vacuum levels as low as 5x(10^-9~10^-10) torr (untrapped). This advanced fluid is not just a product—it’s a catalyst for innovation across industries.

Engineered for Excellence
IOTA 705’s chemical composition, Pentaphenyl trimethyl trisiloxane, ensures superior stability and efficiency. Its specific gravity of 1.090~1.100 and viscosity range of 170~175 cSt at 25°C make it a reliable choice for high-temperature environments. With a flash point of ≥243°C and a congealing point as low as -18°C, IOTA 705 is built to perform in even the most extreme conditions.

A Fluid for Every Application
The versatility of IOTA 705 is truly remarkable. In the electrical and electronics industry, it’s used in the production of TV tubes, capacitors, and rectifiers. In metallurgy, it’s essential for high-vacuum furnaces and thick-film deposition. The optical industry relies on IOTA 705 for surface improvements and anti-reflective coatings, while the plastics industry uses it for protective and film coatings. Its role in R&D plants and mass spectrometry further underscores its importance in cutting-edge research.
