Product Service 1-800-522-7658

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.

Product Service 1-800-522-7658

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

Product Service 1-800-522-7658

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

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.

Please see Chapter 7 to order the pressure relief valve and other valve

accessories for the Precise Basic Glove Box.

Chapter 2: Prerequisites

Product Service 1-800-522-7658

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

determine whether laboratory atmosphere entering the

glove box could result in fire, explosive hazard or damage

to property inside the glove box.

See Figures 3-1, 3-2, and 3-3 in Chapter 3 for ventilation connection

diagrams of the vent kits.

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

Chapter 2: Prerequisites

Product Service 1-800-522-7658

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.

Product Service 1-800-522-7658

Once the site for your glove box is properly prepared, you are ready to

unpack, inspect, install, and validate performance of your system. Read this

chapter to learn how to:
