Description

Inland 19 pump oil is ideal for use in all models of rough vacuum pumps including Alcatel, Edwards, and Welch. Inland 19 utilizes crude stocks known for their durability and fine lubricating qualities.

Inland 19 Pump Oil is an ideal 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.

Beneficial Features:

• Vapor Pressure at 25 °C: 1 x 10-5 Torr
• Boiling Point at .01 Torr: 112 °C (234 degrees F)
• Viscosity at 40 °C: 55 cst (251 SUS)
• Lower vapor pressures
• Reduced backstreaming
• Longer fluid life
• Can be used within the same applications as more expensive diffusion pump oils which could 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.

Inland 19 replaces Inland 15 which has been discontinued by the manufacturer. Inland 19 will provide a decade improvement in pumping efficiency over Inland 15.
