This section explains how to install a Glovebox
3.1 Pre-Installation Requirements
3.1.1 Working Gas
The working gas requirement is Nitrogen, Argon or Helium with a suitable regulator to adjust
pressure to 55-60 psi. The working gas must be connected to the gas inlet on the Glovebox
either by flexible hose or hard copper plumbing to a 3/8" compression connector. Four (4)
cylinders are required: three (3) for purging and one (1) for the final operation of the Glovebox.
Note 1:
Refer to system specific installation requirements for further details. This document was
supplied prior to shipping the system. Please contact your local
MRC
representative if you need
.another copy
Note 2
: The working gas tubing must be 3/8” outside diameter for the entire distance from the
regulator to the working gas connection. Any reductions in tubing diameter will result in
insufficient gas flow for optimum system performance.
3.1.2 Regeneration Gas
Note:
The gas purification system has been regenerated and performance tested to < 1ppm of
O2 ands H2O at our factory prior to shipment. It does NOT need to be regenerated prior to first
use upon installation.
One cylinder of Nitrogen or Argon containing approximately 3 to 7% Hydrogen.
3.1.3 Electrical
All
MRC
, Inc. Glovebox systems are configured to operate using the electrical power standard
.for the region in which the Glovebox has been ordered
Note:
The standard 2-glove system requires 2 electrical outlets, one for the main system power
and one for the power supplied to the power strip inside the Glovebox. Larger systems and those
configured with other options require additional outlets.
3.1.4 System Exhaust
Note:
The Regeneration Gas, Vacuum Pump, and Purge exhausts should be handled in
accordance with your facility’s required specifications.
The regeneration gas exhaust is 3/8" I.D., 19/32" O.D. Tygon tubing. The Vacuum Pump
exhausts are 1" OD tubing. The purge valve should also be vented, 1" Female NPT (manual
purge) or KF-40mm flange (automatic purge).
WARNING:
Proper ventilation of the exhausted gases is imperative as high levels of inert gas
can cause asphyxiation.
