Product: Vac-U-Chamber

Uses Negative Pressure to Eliminate Pump Contamination

 

Allows direct filling of air sample bags

  • Uses negative pressure provided by most personal air sample pumps 
  • Designed to contain SKC sample bags

 

Rugged, heavy-duty construction

  • Will not collapse under vacuum

 

Two sizes available

  • Large for sample volumes up to 8 liters
  • Small for sample volumes up to 1 liter

 

Protects from contamination

  • Sample does not pass through the pump
  • Sample contacts only inert tubing and bag

 

Multiple applications

  • Groundwater testing
  • Soil gas sampling
  • Stack sampling
  • Ventilation studies
  • Hazmat testing
  • Ambient or indoor air
  • EPA Method 0040

 

For Convenient, Reliable Bag Sampling

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 through the pump, both sample and pump 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.

Vapor Intrusion Monitoring - Tips

Soil Gas Sampling

Soil gas sampling can identify underground contamination and trace the source, extent, and movement of pollutants.

U.S. EPA Standard Operating Procedure (SOP) # 2042 for Soil Gas Sampling specifies sample bags as containers inside an airtight chamber (e.g., Vac- U-Chamber). A sample pump creates negative pressure in the chamber, causing soil gas to enter into the bag directly. Samples are analyzed in the field with direct-reading instruments and/ or in a qualified laboratory.

 

ASTM D5314-92 Standard Guide for Soil Gas Monitoring in the Vadose Zone recommends collection by a whole air/sorbent method or a bulk soil/water sample for sampling headspace. Per the standard, the whole air/sorbent method is preferable because headspace sampling has significant disadvantages.
