Santovac oil 5
Diffusion pump fluid. A polyphenyl ether which is capable of near 10-10 torr in an ideal system. Santovac 5 by Santovac Fluids, Inc. has extreme oxidation resistance and produces very low column contamination since it is one of the most radiation-resistant fluids available. Ultra low vapour pressure results in low ultimate pressures; there is no need for a cold trap and it is suitable for diffusion pumps. Tests have shown this fluid to be physiologically inert.
Santovac 5 may discolour with use but it will maintain its physical properties.
