Cryogenic Applications of Apiezon N Grease Cryogenic Vacuum Seal Apiezon N Grease exhibits extremely low vapour pressures at ambient temperatures, 6 x 10-10 torr at 20°C, which are further improved by reductions in temperature to the cryogenic region. Its ability to resist cracking at extremely low temperatures makes it particularly useful as a vacuum seal for cryosystems. Apiezon N Grease can be relied upon to form and maintain a vacuum seal for long periods, even when subjected to frequent thermal cycling, withstanding cycling between temperatures as extreme as -273°C and +30°C. Its unique properties mean N Grease is widely used to create a reliable vacuum and pressure-tight seals in, amongst others: vacuum lines; Schlenk lines; cold traps; liquid helium hoses and electron microscopes. Thermal Coupling Apiezon N Grease has a proven track record in improving thermal contact under cryogenic conditions. This is important for the coupling of cooling systems to superconducting magnets, cryostats, temperature sensors or any system that is required to reach cryogenic temperatures as quickly as possible. Low levels of magnetic susceptibility also make it ideal for superconductor manufacturing applications. Sensor Mounting Apiezon N Grease is ideal for use in cryogenic sensor mounting. It is pliable at room temperature and solidifies at cryogenic temperatures to allow for easy mounting and removal of sensors without causing damage. Sample Mounting Important in low-temperature testing of semiconductor chips, laser diodes and crystals, etc., Apiezon N Grease is used to improve thermal contact between the sample boat and cold finger of a cryotstat.

Apiezon T grease Apiezon T Grease is a silicone-free medium temperature vacuum grease renowned for its quality and tenacity. Apiezon T Grease has gained approval from prestigious organisations including NATO and the US Navy. Apiezon T Grease is a silicone-free medium temperature vacuum grease which: performs well under a wide range of temperatures, from +10 to +120°C is not recommended for highly stressed bearings has added cushioning 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 solvents exhibits a vapour pressure of 4.6 x 10-9 Torr at 20°C As a vacuum grease, Apiezon T Grease is specifically designed for use in the low to medium vacuum range, yet is suitable to be used in the high vacuum range at lower temperatures. We specifically recommend that Apiezon T Grease is used for both sealing and lubrication in medium temperature environments (but not for highly stressed bearings). T Grease confers excellent cohesive strength and therefore when joints are mated they stay mated, forming an extremely efficient, gas tight seal. Apiezon T Grease provides extra cushioning between mated surfaces, and is highly effective in protecting fragile glass to glass joints. The strong absorption properties of Apiezon T Grease give it a powerful ‘gettering’ action . This is of considerable value in the electronics industry where scrupulous cleanliness of metal surfaces is required. Apiezon T Grease has also found a niche as a barrier to oxygen transmission in both vacuum and non-vacuum situations. Apiezon T Grease Vapour Pressure Graph MSDS Technical Data Sheet

Apiezon M grease 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 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 solvents As a high vacuum grease with excellent lubrication properties and radiation resistance, Apiezon M Grease is used for many diverse applications. In particular, M Grease is commonly used in scientific and industrial sealing and lubrication applications. Apiezon M Grease has been especially formulated to provide excellent lubrication while maintaining an efficient gas seal and is therefore widely used in the manufacture and servicing of high performance vacuum pumps. Using silicone-free Apiezon M Grease avoids the problems of ‘creep’ and ‘carry over’ which can often lead to sample contamination. Therefore, it is regularly used in analytical techniques such as infrared or mass spectrometry where sample contamination must be avoided. Similarly, ‘creep’ can cause problems in industrial paint or metal deposition processes as trace amounts of silicone on surfaces can prevent the adherence of paint, leading to poor coverage. When using silicone-free Apiezon M Grease this is not a problem. As a halogen-free product, Apiezon M Grease has a built-in resistance to irradiation. Other high vacuum greases such as esters, silicones or halogenated paraffins decompose at radiation levels of 0.1 MGy or less. In contrast, M Grease maintains excellent lubrication properties in high radiation applications, despite a small increase in stiffness when irradiated with 4 MeV electrons to 1 MGy. Apiezon M Grease has strong powers of absorption, particularly for other hydrocarbon molecules due to its complex hydrocarbon structure and very high molecular weight. Consequently it is frequently used as a stationary phase in gas chromatography. Apiezon M Grease Vapour Pressure Graph MSDS Technical Data Sheet
