Apiezon H Grease, 25g tube
Apiezon H Grease is a silicone-free high vacuum grease perfectly suited for use at high temperatures in both scientific and industrial applications. H Grease has exceptional ‘stiction’ and thermal conduction properties and has gained prestigious approvals from a variety of international organisations, including BAE Systems, the European Space Agency and NASA.
Apiezon H Grease: High Temperature Vacuum Grease Properties.
Apiezon H Grease is a silicone-free high temperature vacuum grease which:
-performs well under a wide range of temperatures, from -10 to +240°C, and retains its optimum consistency at temperatures between +10 and +110°C 
-rather than melting, actually becomes stiffer as temperature increases and therefore is not recommended for highly stressed bearings
-has excellent heat transfer properties
-conducts heat away from the site of operation, reducing the danger of overheating and damaging heat-sensitive components
-exhibits good ‘stiction’ or sticking power
-has powerful ‘gettering’ action, meaning it absorbs potentially harmful grease and chemical impurities on metal and glass surfaces 
-is easy to clean and remove as it is soluble in hydrocarbon and chlorinated solvents
-exhibits a vapour pressure of 1.7 x 10-9 Torr at 20°C
APIEZON L Grease 50 Gms
A well‐proven and recommended high‐vacuum grease for electron beam instruments. Grease L is a petroleum hydrocarbon grease, containing no additives. Very low vapour pressure (@20°C of 8×10‐¹¹ torr), high vacuum grade. Type L is widely used in electron microscopy where moderately high column temperatures and high vacuum requirements demand a vacuum grease with extraordinary characteristics. Type L is 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). Its solubility is as follows: in ethanol at 20°C‐0.003%; 60°C‐0.005%; 100°C‐0.011%; 150°C‐0.011%. Grease L softens and melts at about 47°C and it is not recommended for joints where temperatures exceed more than 30°C in use. Grease T is recommended for these higher temperatures.
Apiezon M Grease, 100g tube
Apiezon M Grease is a silicone- and halogen-free high vacuum grease and is ideally suited to all manner of high vacuum applications. Its inherent versatility means M Grease is also frequently used for non-vacuum purposes in both scientific and industrial settings and it is approved for use by NATO.Apiezon M Grease is designed for use in high vacuum environments at ambient temperatures (generally between 10 to 30°C / 50 to 86°F). If you are looking for a grease capable of performing at higher temperatures, Apiezon AP101 or Apiezon H Grease may be more appropriate.
Apiezon M Grease: High Vacuum Grease Properties
Apiezon M Grease is a silicone- and halogen-free high vacuum grease which:
-does not suffer from contamination problems associated with silicone based greases such as ‘creep’ or ‘carry over’
-provides excellent lubrication
-is recommended for use at ambient temperatures
-exhibits a vapour pressure of 1.7 x 10-9 Torr at 20°C
-has built-in radiation resistance 
-has powerful ‘gettering’ action, meaning it absorbs potentially harmful grease and chemical impurities on metal and glass surfaces
-is easy to clean and remove as it is soluble in hydrocarbon and chlorinated solvents.

Apiezon N Grease, 25g tube
Apiezon N Grease is silicone-free and widely recognised and recommended as the cryogenic vacuum grease of choice. This cryogenic grease is specially formulated to exhibit craze-free performance characteristics at low temperatures and withstand frequent cycling between cryogenic temperatures as low as -273°C and +30°C.
Apiezon N Grease: Cryogenic High Vacuum Grease Properties
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 and chlorinated solvents.
