Ultragrade 19 Vacuum Pump Oil

Mineral oil derivative ideally suited for mechanical rotary vacuum pumps. Light end fractions are removed through molecular distillation resulting in lower vapor pressures and reduced backstreaming compared to undistilled refinery products. Offers reduced maintenance costs, longer fluid life and cooler running.

Suitable for single and dual rotary vane pumps from VRL, Edwards, Alcatel, Adixen, Varian, Agilent, Leybold, Oerlikon, Sargent-Welch, Ulvac, Ilmvac, and other brands.

Santovac® 5 Diffusion Pump Oil

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.

Lion S Diffusion Pump Oil

Lion S diffusion pump oil is a high quality alkyl naphthalene based diffusion pump oil, especially developed for applications such as electron microscopes, mass spectrometers and small vacuum systems. Recommended for TEMs and SEMs made by Hitachi, JEOL and ISI/ABT/Topcon equipped with a diffusion pump.

No need for lower grade substitutes, this is the original LION S diffusion pump oil, manufactured by the Lion Corporation, Japan. It has been and is still used in diffusion pumps used in instruments manufactured in Japan. Lion S diffusion oil has a high resistance against oxidation and works well with small and medium size diffusion pumps.
