Avoid

sampling period, turn o

the pump and close the valve on the bag.
Filling Bags Using Negative Pressure
The SKC Vac-U-Chamber is a rigid air sample box that allows the direct
fi
lling of
an air sample bag using negative pressure provided by most personal air sample
pumps. When using the Vac-U-Chamber, the air sample enters the bag directly,
without passing through the pump. This eliminates the risk of contaminating the
pump or sample. The Vac-U-Chamber has rigid walls that will not collapse under
vacuum conditions, thus eliminating possible errors. All surfaces in contact with
samples are constructed of inert materials.
