Suggested or Recommended Workflow
Once skilled in your lab’s Standard Operating Procedure (SOP), don appropriate
protective garments and gear suitable to the level of safety required. Place items
for use in the procedure in the left section of the work area. Place equipment in
the center of the work area. Designate the right section of the BSC for waste to be
disposed of at the procedure’s end.
As you perform the procedure, waste materials will accumulate on the right side of
the cabinet.
After the procedure is finished, remove waste materials, disinfect as is customary at
your facility, and place materials away. Each time the unit is used, it should be left
clean. Follow your SOP for shut down or night setback procedures.
Night Setback/Low Flow Mode
The Interceptor
®
Biological Safety Cabinet is equipped with a two-speed motor to
save energy when it is not being used for active procedures. The cabinet is placed
into Night Setback/Low Flow Mode by closing the sash to a 1" opening. At 1", the
cabinet exhausts about 50% of the air the unit processes at a 10" opening.
Do not
run active experiments at this 1" sash height.
When the sash is moved to a 1" opening, Night Setback/Flow Flow Mode, the Control
Monitor will look like Figure 4.11 below.
NOTE:
Low flow is set to 50% of run speed. It is not
necessary to calibrate the BSC for this position.
