Santovac 5 Polyphenyl Ether

Vacuum Pump Fluid,

Standard Grade

S

antovac 5 vacuum diffusion

pump fluid operates efficiently,

economically and safely in dif-

fusion 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.

Features:

•

Ultimate Pressure to 10

-10

Torr.

•

Lowest Backstreaming

Characteristics

•

Excellent Thermal Stability

•

High Tolerance to Pressure Bursts

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 stabili-

ty. 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 5 has little

tendency to increase in viscosity during the standard testing. These

results indicate that there is less chance of overheating and thermal

degradation.

Ultra

-high purity Santovac 5 for ultra clean MS applications

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 Edwards E050/060 diffusion pump used on the MSD’s.
