Apiezon N Grease

Apiezon N Grease is a silicone- and halogen-free cryogenic high vacuum grease which:

can withstand frequent cycling between cryogenic temperatures as low as -273°C and +30°C
is craze-free at cryogenic temperatures
has the ability to fill the micropores of adjoining surfaces, so improve thermal contact
does not suffer from contamination problems associated with silicone based greases such as ‘creep’ or ‘carry over’
exhibits a vapour pressure of 6 x 10-10 Torr at 20°C
has powerful ‘gettering’ action, meaning it absorbs potentially harmful grease and chemical impurities on metal and glass surfaces
is easy to clean, use and remove as it is soluble in hydrocarbon solvents
Available to buy in 25g tubes.
