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.
