Connect the Plumbing Lines for Gas, Vacuum,
and Gas Purifiers/Drying Trains
Labconco offers various vacuum and gas tubing installation kits listed in
Chapter 7 for connecting inert gas, vacuum, and gas purifiers to the glove
box. Refer to Figures 3-4, 3-5, 3-6, 3-7, and 3-8 that depict the installation
tubing kits. From Chapter 7, order Gas and Vacuum Tubing Connection Kit
5245100 or 5245200 and install using Figures 3-4 through 3-8. For effective
operation and to prevent overpressurization that can cause glass
breakage, the inert gas line must never be set at a pressure greater than
10-14 psi (69-96 kPa) through the use of a gas supply pressure regulator.
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. Rotary vane vacuum pump model numbers can be
found in Chapter 7 and are required for all models as depicted in Figure 3-7.
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 or vacuum line particulate trap 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).
For ultra low oxygen and moisture purity levels, Labconco recommends the
accessory AtmosPure Re-Gen Gas Purifier shown in Figure 1-1, Figure 1-3,
and Figure 3-7. (See performance results listed in Chapter 1.) See Chapter 7
to order the AtmosPure Re-Gen Gas Purifier. Chapter 7 and Figure 3-7 also
list and depict the AtmosPure Regeneration Plumbing Kit and AtmosPure
Circulation Kit required for proper performance of the AtmosPure Re-Gen
Gas Purifier. Chapter 7 also lists alternative drying trains that reduce oxygen
and moisture. Contact Labconco for further details.
