• Static pressure measured inside the glove box varied from negative .12
inches of water column at 15-CFM to negative 1.28 inches of water at 84-
CFM. The total system static pressure as measured between the exhaust
filter and the blower varied from negative 0.31 inches of water column at
15-CFM to negative 2.48 inches of water at 84-CFM.
• Displacement (vibration level) measured on the work surface is
negligible at minimum through maximum airflow volume settings. The
measured level of displacement ranged from 0.07 x 10
-5
meters to 0.38 x
10
-5
meters.
• Balance stability test results were excellent with no detectable instability
of an analytical balance to five decimal places and a top loader to three
decimal places. Test results were confirmed with the glove box operating
at various airflow volume settings and with various sample weights.
