Product Service 1-800-522-7658 9
WARNING: In the case of failure caused by excessive
vacuum within the main chamber, the user must safely
determine whether laboratory atmosphere entering the
glove box could result in fire, explosive hazard or damage
to property inside the glove box.
Electrical Requirements
Electrical receptacles should be located nearby for connecting the glove box
cords, or other optional laboratory equipment. Single width units require two
line cords and double width units require three line cords. Line cords are
each rated at 100-115V, 12A or 230V, 12A. The entire glove box is rated
115V, 12A or 230V, 12A or 100V, 12A. One outlet is located inside the
glove box and is rated for 115V, 10A or 230V, 10A or 100V, 10A. The
exterior vacuum pump outlet is rated 100-115V, 12A or 230V, 6A.
Doublewide models have an additional outlet, located inside the center of the
glove box and is rated for 115V, 10A or 230V, 10A or 100V, 10A.
Additional power strip accessories are available and can be connected to the
interior receptacle outlet (see Chapter 7).
Plumbing Requirements for Inert Gas, Vacuum,
and Gas Purifier/Drying Train
The Protector Controlled Atmosphere Glove Box has two valves located on
the main glove box chamber and two valves located on the transfer chamber.
The two valves on the main chamber should be used for the operation of the
main chamber inert gas inlet and vacuum outlet lines. For effective operation
and to prevent overpressurization that can cause glass breakage, the gas inlet
lines 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 two valves on the
transfer chamber are used for inert gas inlet and vacuum outlet lines. The
transfer chamber lines can be connected together with the main chamber gas
inlet and vacuum outlet lines to simplify gas and vacuum connections to both
chambers. On the rear of the Protector Glove Boxes, there are two 3/4"
compression fittings for connection to an accessory AtmosPure Re-Gen Gas
Purifier or other drying train. The Gas Purifier per Figure 1-1 in Chapter 1 is
used for the removal of oxygen and moisture from the main chamber
atmosphere. Other drying trains can be used to remove organic vapors, acids,
ammonia, or radioisotopes. See Chapter 7 for ordering information and
Chapter 3 for setup. Illustrations for gas, vacuum, and gas removal
accessories are shown in Chapter 3.
