Apiezon AP100 grease is a silicone-free vacuum grease and lubricant containing PTFE.

• Anti-seize properties, making it an effective protector and lubricant in ultra-high vacuums
• Exhibits extremely high levels of lubricity
• Demonstrates an extremely low vapour pressure of 7 × 10^-11 Torr at 20 °C
• Recommended for use at ambient temperatures
• Does not suffer from contamination problems associated with silicone based greases such as creep or carry over
• Easy to clean and remove using hot water and an aqueous glassware detergent or hydrocarbon solvents

AP100 exhibits extremely high levels of lubricity and has been shown to provide eight times the level of lubrication offered by standard, petroleum-based lubricating greases. Apiezon AP100 is designed for use 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.
