  • Information

Inland 19 is Inland Vacuum’s recommended general-purpose hydrocarbon fluid for mechanical vacuum pumps used in non-corrosive applications. The manufacturing process of Inland 19 includes molecular distillation, which removes light end fractions present in the fluid and gives it the desired properties: lower vapor pressures, reduced back streaming, and longer fluid life. As a result, it can be used within the same applications as more expensive diffusion pump oils which would otherwise be contaminated by a vacuum oil of lower grade. A durable, long-lasting mechanical pump fluid, Inland 19 is cost-effective in vacuum applications such as mass spectrometers, electron microscopes, thin-film sputtering, UHV systems, and freeze dry systems. Proper use of this oil effects reduced maintenance costs, improved pumping cycles, and a cleaner vacuum system.
