Features and Benefits:
Apiezon N grease is the first choice sealant and heat transfer medium for low temperature applications. Being pliable at room temperature but freezing solid at cryogenic temperatures, it allows for easy mounting and removal of sensors or samples without causing damage.
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. This cryogenic thermal contact grease ensures that samples are at the lowest possible temperatures to improve test sensitivities.
Apiezon N Grease can also be used in a variety of applications at ambient temperatures such as when added cushioning is required. N Grease has a special additive which gives it a tenacious, rubbery consistency which absorbs vibrations in equipment, making N Grease invaluable in fragile glass to glass joints, like burette taps, which continually risk fracture
