S
antovac 5 vacuum diffusion
pump fluid operates efficiently,
economically and safely in diffu-
sion pumps, in properly designed sys-
tems, to produce ultra-high vacuums in
the 10
-10
torr range. The wide liquid
range, low vapor pressure and unique
balance of properties make it an ideal
working fluid in diffusion pumps.
Santovac 5 is a light colored, slightly vis-
cous liquid at room temperature.
Santovac 5 is an isomeric mixture of five-ring polyphenol ethers.
Low Vapor Pressure
Extremely low vapor pressure results in low ultimate pressures.
The vapor pressure of Santovac 5 at 25°C determined by extrapo-
lation of higher temperature data is 4 x 10
-10
torr. This, together with
low backstreaming characteristics, means that 10
-10
torr vacuums
can be obtained in well designed systems without the use of liquid
nitrogen traps.
Low Backstreaming
Oils have inherently low backstreaming characteristics. Low
backstreaming can result in less contamination in chambers and
longer term operation for those processes that are sensitive to
organic matter. Experience has shown us that polyphenyl ether
type fluids like Santovac 5 pump fluid can be used for electronic
component manufacture, and for laboratory, analytical instrumental
and research applications.
High Thermal Stability
Santovac 5 offers unusually high thermal and oxidation stabil-
ity. Isoteniscope tests show that they remain thermally stable at
870°F. Santovac 5 may discolor with use, but this does not affect its
operation as a diffusion pump fluid. Oxidation and corrosion tests,
as well as field experience, have shown that Santovac 5P has Little
tendency to increase in viscosity during the standard testing. These
results indicate that there is less chance of overheating and thermal
degradation.

N
ow there is a higher grade of Santovac 5 diffusion pump
fluid. Santovac 5 has been the fluid of choice for diffu-
sion pumps for many years and now an improved grade
of fluid is available. Santovac 5P Ultra has the same properties of
Santovac 5 but guarantees minimal amounts of the 3 and 4 ring
polyphenyl ethers; less than .02% and .1% respectively. This
makes Santovac 5P Ultra the fluid of choice for ultra-clean applica-
tions such as mass spectrometry. Santovac 5P Ultra is the standard
diffusion pump fluid recommended by Agilent (Agilent #6040-0809).
So if you require the best try Santovac 5P Ultra.
An 18.5 ml single charge bottle of Santovac 5P is now available
for the Agilent MSD diffusion pumps. Just the right amount required
for the BOC Edwards E050/060 diffusion pump used on the MSD’s.
