Overview

This synthetic fluid is a polyphenyl ether developed from fluids originally produced as lubricants for space vehicles. It has exceptionally low vapour pressure, exceptional thermal stability and a tendency to wet surfaces less readily and 'creep' to a lesser extent than is common with most fluids. The fluid is employed for the cleanest high vacuum and ultra high vacuum applications down to less than 10-9 mbar (for example, electron microscopes, mass spectrometers and surface physics studies) where its excellent high vacuum performance and low tendency to migrate into the pump system particularly recommend it. The fluid is chemically stable, non-corrosive, safe and non-toxic at normal operating temperatures. Fluid breakdown products (due to bombardment and so forth) tend to be electrically conducting.

Applications

  • Mass spectrometers
  • Electron microscopes
  • Thin film sputtering
  • Surface studies
  • UHV systems
  • Leak detection
  • Power valves
  • Space studies
  • Radioactive

Features and Benefits

  • It has exceptionally low vapour pressure, exceptional thermal stability and a tendency to wet surfaces less readily and 'creep' to a lesser extent than is common with most fluids. The fluid is chemically stable, non-corrosive, safe and non-toxic at normal operating temperatures. Lubricating qualities are good and the fluid finds application to lubricate mechanisms in vacuum systems.
  • Use high purity Santovac® P5 Ultra for the most exacting mass spectrometry applications.
