A
ll stopcocks and movable joints in a high vacuum
system must be satisfactorily lubricated, yet leakproof.
The lubricant for such joints must not, obviously,
contribute to the pressure within the system and must therefore be
of extremely low vapor pressure at the temperature of operation.
Also, the lubricant must be stable, easily applied and preferably
easily removed when desired. Finally the lubricant must lubricate,
an obvious statement but a necessary one since so many
so-called high vacuum lubricants have in fact very poor lubrication
properties.
All these desirable properties are to be found in the Apiezon
greases. By virtue of their low vapor pressures and high purity the
possibility of sample contamination when using Apiezon greases
by “carry over” or adsorption is much reduced, and consequently
the risk of interference in infrared and mass-spectra analysis is
avoided.
Apiezon Grease L
Grease L is a good, general purpose, high vacuum grade with
an estimated vapor pressure at 20°C of 8 x 10
-11
torr. It may be
used on all ground joints in a vacuum system where it is essential
to have a grease with good lubricant properties combined with an
exceptionally low vapor pressure. Grease L softens and melts at
about 47°C and is not recommended for joints likely to warm to
over 30°C.
Of the Apiezon greases, Grease L has proved particularly
popular as the stationary liquid phase in gas-liquid chromatogra-
phy.
Apiezon Grease H
This grease, the latest addition to the Apiezon range of
greases, will withstand temperatures up to 250°C without melting.
In fact, it stiffens somewhat above 40°C, Vapor pressure is
estimated to be 2 x 10
-9
torr at 20°C. It is of a rubbery nature and
is intended for the same applications as Grease T but where
higher operating temperatures, are required. Grease H can be
used at ambient temperature, and down to approximately -15°C
but at this temperature it becomes sticky and is no longer a good
lubricant.
Apiezon Grease M
This grease has an estimated vapor pressure at 20° C of
2 x10
-9
torr, higher therefore than Grease L, and is used where a
grease of such moderately low vapor pressure is adequate. It is
used whenever a good lubricant is required and, being much
cheaper than the other Apiezon greases, is recommended for use
not only in vacuum work but as a good lubricant for general use
throughout the laboratory.
As with Grease L, Grease M is not intended for use with joints
above 30°C.
Apiezon Grease N
Grease N has been designed specifically for the lubrication of
glass conical taps and similar joints where its rubbery nature
allows the grease to form a cushion between the mating surfaces,
thus acting as a highly effective lubricant while maintaining its
function as a sealing medium. Grease N has an estimated vapor
pressure at 20°C of 8 x 10
-10
torr, and, as with greases M and L, is
recommended for use up to temperatures of about 30°C.
Apiezon Grease T
Also of a rubbery nature, Grease T is designed for lubricating
glass taps and for general purposes where operating temperatures
necessitate the use of a relatively high melting point grease.
Grease T melts at 125°C and has an estimated vapor pressure at
20°C of 5 x 10
-9
torr. Although Grease T is particularly useful at
higher temperatures it can also be used at ambient temperatures
and may therefore be applied and used at temperatures between
0° and 120°C.
Apiezon AP Anti-Seize Greases
These two greases are specifically designed to prevent
ground-glass, stop-cocks, and taps from jamming. For these
applications type AP greases have been found to be markedly
superior to other lubricants such as petroleum jellies and silicones.
As a result they are ideal lubricants for general laboratory use.
Packed in tubes for ease of application, AP
greases can be
easily removed by wiping with a soft cloth or washing with an
aqueous glassware detergent.
Apiezon Grease AP 100: A high vacuum grease with a
softening point of 30°C. Vapor pressure is estimated to be
8 x 10
-11
at 20°C.
Apiezon Grease AP 101: A general purpose stop-cock grease
suitable for moderate vacuum use with a very wide range of tem-
perature from -40°C to 180°C. Vapor pressure is estimated to be
5 x 10
-6
at 20°C.
