Labconco Protector Controlled Atmosphere Glove Boxes 5080102 - Manual (Page 29)

NORMAL OPERATION
30
NOTE: Notice that the pressure gauge changes drastically when the gloves are pulled inward or
outward. When selecting operating pressure, this must be considered to, ensure operating limits of
± 5" water column are not exceeded.
CAUTION: On Models 5060000 and 5060100 all valves must be closed when the glove box is
unattended.
To further reduce the moisture level, the optional Drying Train (Catalog #50613) may be
installed.
Transfer Procedure (Models 5060000, 5060100, 5070000 and 5070100:
1. Transfer from laboratory into glove box – Make sure the inner chamber door is closed.
Place material into the transfer chamber and close the outer transfer chamber door.
Transfer from glove box outward to laboratory – Make sure the outer door is closed. Place
material into the transfer chamber and close the inner door.
2. Turn on the vacuum pump and open the vacuum valve. Purge the chamber to the vacuum
level you have selected. Close the vacuum valve. Open the chamber “gas fill” valve and
monitor the glove box pressure if backfilling from the glove box. Do not exceed the
atmospheric pressure within the transfer chamber.
3. Repeat Step 2 as required for your operation.
4. When final backfill sequence is completed (the vacuum gauge has returned to zero
reading), open the inner or outer chamber door (depending on the direction of transfer) and
remove or position the material. Close and latch the appropriate door.
NOTE: The level of purge vacuum and the number of purge/fill sequences is determined
by the operator.
Transfer Procedure (Models 5080000 and 5080100 with Purge/Fill Control Module):
1. Transfer from laboratory into glove box - Make sure the inner chamber door is closed.
Place material into the transfer chamber and close the outer transfer chamber door.
Transfer from glove box outward to laboratory – Make sure the outer door is closed. Place
material into the transfer chamber and close the inner door.
2. Purge/Fill Cycle – On Model 5080000 and 5080100, these sequences are performed
automatically. To review the information, refer to the previous section, Operation of
Controls. See section on Transfer Chamber and Valves, page 27.
3. When final backfill sequence is completed as indicated by the “End” light, open the inner
or outer door and remove or position the material (depending on the direction of transfer).
Close and latch the appropriate door.
