Key Features and Applications of IOTA 705 Diffusion Pump Oil IOTA 705 Diffusion Pump Oil is a premium-grade fluid renowned for its ultra-low vapor pressure and excellent thermal and oxidative stability. With a viscosity range of 170-175 mm²/s at 25°C and a refractive index of 1.5765-1.5785, this oil is perfect for high-vacuum applications. Its low freezing point (≤-14°C to -18°C) and high flash point (≥243°C) ensure reliable performance in extreme conditions. IOTA 705 is widely used in industries such as high-vacuum metallurgy, electron tube manufacturing, and atomic energy research. Packaged in 1 kg, 5 kg, 25 kg, 50 kg, and 200 kg containers, it is easy to transport and store, with a shelf life of up to three years.
