Why Choose IOTA 705 for Ultra-High Vacuum Applications? IOTA 705 is a top-tier diffusion pump oil designed for ultra-high vacuum environments. Its key properties include a low saturated vapor pressure (<3 x 10^-10 torr) and a high flash point (≥243°C), ensuring minimal outgassing and excellent thermal stability. With a viscosity of 170-175 mm²/s at 25°C and a refractive index of 1.5765-1.5785, this oil is ideal for applications requiring precise vacuum control. It is widely used in high-vacuum metallurgy, electron microscopy, and atomic accelerators. Available in various packaging options, IOTA 705 is easy to handle and store, making it a reliable choice for industries demanding high-performance vacuum solutions.
