Chapter 5: Using Your Glove Box

Product Service 1-800-522-7658

• Objects in contact with previously contaminated internal atmospheres

must be surface decontaminated or bagged before removal from the

glove box through the transfer chamber.

• After placing materials to be removed in the transfer chamber and

locking the internal door, the transfer chamber must be evacuated and

filled approximately 1-5 times depending on vacuum level achieved.

This ensures the removal of any remaining airborne contaminants

before the outer door is opened. Never apply a high vacuum purge on

sensitive electronic moisture and oxygen monitors. The exact number

of cycles should be determined by your Safety Officer.

Shutdown

• To help preserve the controlled atmosphere, leave the glove box main

chamber under slight pressure differences and continuously run the

AtmosPure Re-Gen Gas Purifier. The use of the accessory external

glove port covers can assist in preserving the inert atmosphere.

• Keep the outer door closed when not in use.

Hazardous Use with Chemicals

Hazardous chemicals may be used safely only when the glove box

vacuum pump and pressure relief bubbler are both properly vented

and/or filtered to the outside. Consult your Safety Officer for proper

venting and filtering of the vacuum pump exhaust and the pressure relief

valve for your application.

Prohibited Acid Use

On stainless steel models, the glove box interior must not be exposed to

mineral acid use. The glove box life span will be limited with use of mineral

acids.

NOTE: Labconco makes no claims about corrosion resistance of the

glove box with mineral acid use and warranties will become

void.

Auto Pressure Controller Operation

The Auto Pressure Controller performs three automatic modes on the glove

box. First, it cycles the evacuating/filling process in the main glove box

chamber up to 499 cycles and in the transfer chamber up to 199 cycles.

Second, it regulates vacuum/pressure between -5 and +5 inches of water

gauge in the main glove box chamber through the glove box pressure control

program mode. Third, it regulates vacuum in the transfer chamber between 0

and -29 inches of mercury during the evacuating/filling process.
