Invoil C, formerly Apiezon C Oil (previously M003) (EMS)
Apiezon OILS
Consist of esters or specially selected hydrocarbon fractions. They were developed for vapour-diffusion pump fluids:
- High purity, very low pressure, very stable.
- Pressures lower than 10-7 torr obtainable
- No need for cold trap.
- Good pumping speed.
- No corrosive deposits or vapours.

INVOIL C (formerly APIEZON OIL C)
Obtains the highest vacuum pressure (10-7 torr) of the Apiezon oils without the need of a cold trap. Suitable for most diffusion pump applications, including in electron microscopes and in vacuum coaters. This is an economic and effective substitute for Santovac 5 fluid. It should be noted that the ultimate vacuum is dependent on a suitably high backing vacuum and the out-gasing of TEM film and column components. Consequently the ultimate vacuum attained with Invoil C (Apiezon C) is very close to the theoretically much superior Santovac 5.
This product is not hazardous and does not require an MSDS.
