Product Category Description:

Silicone-free greases for lubricating stopcocks and movable joints in vacuum systems such as desiccators, rotary evaporators, vacuum traps, and ground glass joints. They demonstrate “gettering” properties (the ability to extract chemical impurities), hence are well-suited to electronic applications as they remove organic impurities from a metal surface and do not form insulating films.

Apiezon H, L, M, N, and T greases consist of distilled, petroleum-based, complex hydrocarbons. Vapor pressure curves are available for each product over its working temperature range.

Within the Apiezon range there is a grease designed to suit most applications. L and M greases are particularly good lubricants, with L grease being recommended for ultra high vacuum systems and M in slightly less critical, high vacuum systems. Both products show resistance to irradiation. Structural properties make L and M greases effective as a stationary phase in gas-liquid chromatography. Both N and T greases display a rubbery consistency and work well as cushioning lubricants. N grease is specifically for use in cryogenic applications, whereas T grease is for higher temperature vacuum applications up to 120°C (248°F). The thermal conductivity properties and high temperature resistance of H grease allow its use at temperatures up to 240°C (464°F).

Ordering Information: Packaged in aluminum tubes to prevent contact with the atmosphere and reduce contamination from dust or water.
