SANTOVAC fluid is often used as a vacuum diffusion pump fluid and operates efficiently, economically, and safely to produce ultra-high vacuum of 5 x 10-10 torr or greater, at 25°C. Diffusion pumps are the most economical and reliable means of reaching such low pressures and SANTOVAC 5 has proven to be, without a doubt, the best pump fluid available for this type of equipment.
