Apiezon L vacuum grease (EMS)
Apiezon L ultra high vacuum grease is a well-proven and recommended high-vacuum grease for electron beam instruments. It is a petroleum hydrocarbon grease, containing no additives. Very low vapour pressure, high vacuum grade. Widely used in electron microscopy where moderately high column temperatures and high vacuum requirements demand a vacuum grease with extraordinary characteristics and also used in the stationary phase of gas liquid chromatography, and may be used on all ground joints in a vacuum system (not for stopcocks).
