Invoil 704 is a single component silicone diffusion pump fluid for high vacuums 10-6 to 10-8 torr range. This diffusion pump fluids' low vapor pressure and thermal stability make it popular in many systems such as mass spectrometers and electron microscopes. It performs well in most applications and offers quick pumpdown, even after exposure to air under operating conditions.
