Santovac 5 is polyphenyl ether synthetic diffusion pump fluid capable of producing ultra-high vacuum in the 10-10 mbar range. Due to this fluid’s extremely low vapor pressure, backstreaming characteristics are lower than any other fluid resulting in less contamination and longer operation. Santovac 5 has exceptionally low volatility and is thermally stable, non-halogenated water white fluids. It exhibits extraordinary resistance to degradation from heat, oxygen, radiation and chemical attack. This lubricant is designed for applications where extremely high temperatures and adverse environments are expected. It is compatible with most metals and elastomers commonly used in vacuum pumps.

Santovac 5 is ideal for use in many applications including laboratory, analytical and research operation, vacuum production, thin films, space simulation chambers, and optical coatings.
