<strong>Vacuum</strong> Greases<br />
RAMSAY greases<br />
for lubricating ground joints and drain<br />
valve in fore-vacuum lines consist of<br />
special grades of paraffin jelly to which<br />
caoutchouc is added for attaining the<br />
specific consistence.<br />
RAMSAY grease thick<br />
is used to lubricate ground joints.<br />
Usable down to 10 -2 mbar/Torr.<br />
RAMSAY grease soft<br />
is used to lubricate drain valves.<br />
Usable down to 10 -2 mbar/Torr.<br />
GLEITLEN<br />
is a special grease used to lubricate<br />
stirrer shafts (KPG stirrers, among<br />
others) of all sizes in the laboratory.<br />
Usable down to 10 -2 mbar/Torr.<br />
LITHELEN<br />
contains lithium compounds, and all<br />
components contributing to higher<br />
vapor pressures have been removed<br />
through high-vacuum pre-processing.<br />
It may be used within a wide temperature<br />
range (from 0 °C to 150 °C<br />
(32 °F to 302 °F)) and in all applications<br />
from atmospheric pressure down<br />
to 10 -8 mbar (0.75 x 10 -8 Torr).<br />
Silicone high-vacuum grease<br />
Dow Corning<br />
contains compounds of a high<br />
molecular weight together with chain<br />
elements containing silicon and<br />
oxygen.<br />
At temperatures over 220 °C (428 °F)<br />
the silicone grease will polymerise<br />
giving off gas. It may be used within a<br />
wide temperature range (from -40 °C<br />
to 200 °C (-40 °F to 392 °F)) and in all<br />
applications from atmospheric pressure<br />
down to 10 -6 mbar/Torr.<br />
DYNAFAT<br />
is used to lubricate gaskets.<br />
Safety data sheets are available to professional users from:<br />
