Applications
Description
The SKC Vac-U-Chamber is a rigid air sample box that allows
sample bags to be filled directly by using negative pressure
provided by most personal air sample pumps. Because the sample
does not pass directly through the pump, both pump and sample
contamination are eliminated. All surfaces in contact with the
sample are constructed of inert materials. The Vac-U-Chamber’s
rigid walls will not collapse under vacuum conditions.
• Groundwater testing
• Soil gas sampling
• Stack sampling
• Ventilation studies
• Hazmat testing
• Ambient or indoor air sampling
• EPA Method 0040

Vac-U-Chamber
Eliminates Pump Contamination During Bag Sampling
Using the Vac-U-Chamber
Ordering Information
The Vac-U-Chamber is equipped with three 1/4-inch OD fitting
ports for inflating sample bags:
Large Vac-U-Chamber
• Sample inlet port for connecting to the sample line or
gas source
• Purge port for purging the air prior to sampling or when
preparing the bag for a standard
• Vacuum port for inflating a bag
An air sample bag is connected to the inside sample inlet port
and the chamber is closed, providing an airtight seal. An air
sample pump is connected to the outside vacuum outlet port.
When activated, the pump evacuates air from inside the chamber. The sample bag inflates as a result of the interior pressure
drop. This pneumatic technique allows the air sample to enter
the bag directly without passing through the pump, protecting
the pump from sample contaminants and the sample from pump
contaminants.
