These two grease are specifically designed to prevent ground glass or polished glass joints in laboratory apparatus from seizing together, particularly in systems containing solvents.  For these applications type AP greases have been found to be superior to silicones and petroleum jellies.  As a result, AP greases are ideal lubricants for general laboratory use.  Packed in tubes for ease of application, AP greases can be removed by wiping with a soft cloth or washing in an aqueous glassware detergent.

AP 100

A blend of very low vapor pressure hydrocarbons and polytetrafluoroethylene (PTFE) lubricant. PTFE is virtually insoluble in all solvents.  AP 100 is a high vacuum grease with a softening point at 30ºC.
 

AP 101

This product is based on a heavy duty lubricating grease gelled with lithium stearate (a silicone earth), and PTFE, and can be used over a wide range of temperatures (-40ºC to 180ºC).
