Pentaphenyl trimethyl trisiloxane makes this top-of-the-line fluid an excellent choice!

Features

Its low vapor pressure and low backstreaming rate make LN₂ traps unnecessary for pressures in the 10^-8 Torr range
With first class LN₂ traps, the ultimate pressure can reach 10^-11 Torr
The high stability and high spontaneous ignition temperatures of this top-of-the-line diffusion pump fluid make it ideal for use in space-simulation chambers
Applications include thin film coating systems, inexpensive surface science systems, and plasma physics research

NOTE: Do not use silicone fluids in mechanical pumps.
