Congratulations on your purchase of a Labconco Precise® Controlled
Atmosphere Glove Box or Precise® Basic Glove Box manufactured with a
one-piece molded polyethylene liner. The Precise Controlled Atmosphere
Glove Box comes equipped with six valves, pressure relief valve and two
chamber pressure gauge indicators, which are omitted from the Precise Basic
Glove Box. The Precise Basic Glove Box allows the end user to customize
the glove box to their application needs or use the glove box in its simplest
form. Both glove boxes are designed to provide an effective physical barrier
between the laboratory and the glove box interior. The barrier provides three
distinct advantages. First, it helps protect the technician from hazardous
materials. Second, it protects materials and laboratory equipment inside the
main chamber from the effects of exposure to ambient air, oxygen, and
moisture levels. Third, it provides a protective, leak-tight environment for
your research, testing, or production procedures; the leak rate of the glove
box is rated Class 1 for controlled atmosphere chambers per ISO 10648-2 test
methods. Each Precise Controlled Atmosphere Glove Box or Precise Basic
Glove Box is helium leak tested at the factory to ensure no leaks greater than
1 x 10
-4
cc/sec.
The Precise Glove Boxes offer many unique features to enhance
performance. To take full advantage of them, you must read and understand
this manual and keep it handy for future reference. If you are unfamiliar with
how the Precise Glove Boxes operate, please review Chapter 4: Performance
Features and Safety Precautions before you begin working in the glove box.
Even if you are an experienced user, please review Chapter 5: Using Your
Glove Box so you can use the glove box efficiently.

Before you install the glove box, you need to prepare your site for
installation. You must be certain that the area is level and of solid
construction. In addition, a dedicated source of electrical power should be
located near the installation site to power the glove box. Additionally, the
glove box should be strategically placed in the lab to provide efficient
workflow and prevent operator interference from normal traffic flow.
Carefully read this chapter to learn the requirements for your installation site:
• The support, vibration and preventive requirements.
• The location requirements.
• The exhaust requirements for the pressure relief valve.
• The electrical power requirements.
• The plumbing requirements for gas, vacuum, and dry train.
• The space requirements.
Refer to Appendix B: Precise Glove Box Dimensions for complete glove box
dimensions.
Refer to Appendix C: Precise Glove Box Specifications for complete
electrical and environmental conditions, specifications and requirements.

Chapter 2: Prerequisites
Support, Vibration and Preventive Requirements
In the preparation of a glove box site, please consider the following:
• A bench or stand that is rigidly mounted to the floor or fixed to the wall,
but not both, may be appropriate. 35" to 40" (889mm to 1,016mm) is
typical for standing height (Labconco stands offered in Chapter 7 vary
from 33" to 40" or 838mm to 1,016mm).
• The corners of a building typically have less vibration than the center,
which promotes analytical balance stability.
• The bench typically should not contain any vibration-producing
equipment, such as shakers or pumps.
• A marble slab with dampening pads placed within the enclosure is an
effective low cost means of controlling vibration for analytical balance
operation (see Chapter 7: Accessorizing Your Glove Box).
Location Requirements
The Precise Glove Boxes have been designed to rest on a typical 29"-30"
(737mm-762mm) deep work surface. The height should be 35"-40" for
standing position. Avoid placing the glove box in high traffic areas where
walking might disrupt the operator or experimentation.
Exhaust Requirements for the Pressure Relief
Valve
To prevent over or under pressurization of the main glove box chamber, the
Precise Controlled Atmosphere Glove Box includes a pressure relief valve
that activates at pressures and vacuums above +6" water gauge or below -6"
water gauge.
WARNING: The overpressurization of air at positive
pressure would allow any contaminants inside the glove
!
Please see Chapter 7 to order the pressure relief valve and other valve
accessories for the Precise Basic Glove Box.
box to vent into the room. To control this venting into the
laboratory, Labconco offers three pressure relief valve
ventilation accessories. All three of these pressure relief
valve ventilation accessories are shown in detail in Chapter
3 and can be ordered from Chapter 7.
Product Service 1-800-522-7658

Chapter 2: Prerequisites
The first option for venting the pressure relief valve is for ducting unfiltered
air to the outside via a 4" nominal diameter exhaust duct. The second and
third options for venting the pressure relief valve will add HEPA filters
and/or carbon filters to the exhaust duct and allow the vented air back into the
laboratory or to the outside. The HEPA filtered and carbon filtered pressure
relief vent kits may be combined if so desired. All pressure relief valve vent
kits include a 4" diameter thimble duct connection to aid in the connection to
the building exhaust blower preventing the pressure relief valve from
activating due to the negative pressure of the building exhaust. Labconco
offers accessory remote blowers listed in Chapter 7 for your convenience in
venting the pressure relief to the outside. These blowers have a 6" diameter
nominal inlet and a 4" x 6" duct transition is necessary to adapt from the 4"
diameter thimble connection provided with all relief valve kits.
WARNING: In the case of failure caused by excessive
vacuum within the main chamber, the user must safely

See Figures 3-1, 3-2, and 3-3 in Chapter 3 for ventilation connection
diagrams of the vent kits.
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,
or other optional laboratory equipment. The entire glove box is rated 115V,
8A or 230V, 4A or 100V, 8A. One duplex outlet is located inside the glove
box and is rated for 115V, 5A or 230V, 2A or 100V, 5A. Additional power
strip accessories are available and can be connected to the interior duplex
outlet (see Chapter 7).
Plumbing Requirements for Gas, Vacuum, and
Drying Train
The Precise Controlled Atmosphere Glove Box has four valves located on the
main glove box chamber and two valves located on the transfer chamber.
Two of the four valves on the main chamber should be used for the operation
of the main chamber gas inlet and vacuum outlet lines. To prevent
overpressurization, the gas inlet lines should be set at a pressure of 10-30 psi
through the use of a gas supply pressure regulator. The other two valves on
the main chamber can be used for connections to a recirculating drying train.
Drying trains are recirculating contaminate removal traps, powered by
vacuum pumps. They are used for the removal of oxygen and/or moisture
from the main chamber atmosphere. They can also be used to remove
organic vapors, acids, ammonia, or radioisotopes. See Chapter 7 for ordering

Product Service 1-800-522-7658
Chapter 2: Prerequisites
optional drying train removal traps. The two valves on the transfer chamber
are used for 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. Illustrations
for all gas, vacuum, and recirculating drying trains are shown in Figures 3-5
through 3-10 in Chapter 3.
All valves utilize 3/8" (9.5mm) compression fittings or 3/8" (9.5mm) hose
barbs for soft tubing. Both styles are offered for your convenience.
Accessory gas and vacuum tubing kits are described in Chapter 7. Should
you require automatic chamber pressure controls, see Chapter 3 for details on
the accessory Pressure Controller and Chapter 7 for ordering information.
The Pressure Controller automatically monitors and controls pressures in
both the main chamber and transfer chamber; it also automates the operation
of purging and filling each chamber (gas outlet and gas inlet) up to 199
cycles. Consult your Safety Officer should you require ventilation and/or
filtration of the vacuum pump exhaust. Filtered exhaust (0.2 micron) and
contaminate removal traps are available for the vacuum pump (see Chapter
7). See Chapter 3 for typical installation of vacuum outlet and inert gas inlet
lines and Appendix H for plumbing diagrams.
See Chapter 7 to order any valves and/or pressure/vacuum gauges for the
Precise Basic Glove Box as these features have been omitted to enable the
end user customization.
Space Requirements
The dimensions are shown in Appendix B: Dimensions. Adequate space to
the right of the transfer chamber is required for loading and unloading.

Chapter 3: Getting Started
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.
