Santovac® 5 Diffusion Pump Oil

  Santovac^® 5 Diffusion Pump OilSantovac^®5 Polyphenyl Ether Vacuum Pump Fluid
excellent for TEM, SEM

Operates efficiently, economically and safely in diffusion pumps in properly designed systems to produce ultra-high vacuums in the 10-10 torr range. A wide liquid range, low vapor pressure and balance of properties make it an ideal working fluid in diffusion pumps. Extremely low vapor pressure results in low ultimate pressures. The vapor pressure of Santovac® 5 at 25°C is 4 x 10-10 as determined by extrapolation from higher temperature data. Together with low backstreaming characteristics, 10-10 torr vacuums can be obtained in well designed systems without the use of nitrogen traps.

Low backstreaming. Santovac® 5 pump fluid can be used for electronic component manufacture, laboratory, analytical, instrument and research applications. Santovac® 5 offers unusually high thermal and oxidation stability, with isoteniscope tests showing thermal stability at 465°C (870°F). May discolor with use but this does not affect its operation. Oxidation and corrosion tests, and field experience have shown that Santovac® 5 has little tendency to increase in viscosity during use. Shelf life, in amber glass bottle at ambient temperatures, is up to 40 years
