Connect the Plumbing Lines for Gas, Vacuum,
and Drying Train
Labconco offers various vacuum and gas tubing installation kits listed in
Chapter 7 for connecting gas and vacuum line, or drying train to the glove
box. Refer to Figures 3-6, 3-7, 3-8, 3-9, and 3-10 that depict the installation
tubing kits. The primary connecting method involves the use of 3/8" O.D. x
3/16" I.D. tubing for gas and vacuum line connections; a tube support insert
must be placed inside the soft tubing to prevent the tube from disconnecting.
The alternative connecting method uses a tube connector and hose clamp
instead of a tube support insert. See Figure 3-5 (A and B) for both methods.
Consult Figure 3-8, which depicts typical tubing connections with the
accessory Automatic Pressure Controller. Vacuum pump model numbers can
be found in Chapter 7. Consult your Safety Officer to determine the
suitability and requirement for venting the exhaust port of a vacuum
pump to the outside. An accessory 0.2 micron filter can be installed in the
vacuum line to prevent particulate material contamination of the vacuum
pump. The 0.2 micron filter can also be installed in the inert gas supply line
connected to the main chamber and transfer chamber to insure a particulate
free gas supply (see Chapter 7). If required, other accessory chemical traps
can also be added to the vacuum line to prevent vacuum pump contamination
(see Chapter 7). Refer to Appendix H for typical plumbing diagrams.
