Vac-U-Chamber

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 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.

  • Allows direct filling of SKC air sample bags
    • Uses negative pressure provided by most personal air sample pumps
  • Protects sample pump from contamination
    • Sample does not pass through the pump
    • Sample contacts only inert tubing and bag
    • Sample line extends from contaminant source through case to bag
  • Rugged heavy-duty construction
    • Will not collapse under vacuum
    • Airtight
  • Four sizes available:
    • Small for sample volumes up to 1 L, 305x229x127 mm
    • Large for sample volumes up to 8 L, 483x356x198 mm
    • Extra-large for sample volumes up to 10 L, 740x460x265 mm
    • Jumbo for sample volumes up to 25 L, 784x660x394 mm

Applications:

  • Industrial VOCs
  • Indoor air quality
  • Effluent gas samples
  • Ground water testing
  • Stack sampling
  • Ventilation studies
  • Hazardous Material (HazMat) testing

 

Using the Vac-U-Chamber

Vac-U-Chamber in Use

The Vac-U-Chamber is equipped with three ¼ inch OD fitting ports for inflating sample bags:

  • 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.

Vac-U-Tube

The SKC Vac-U-Tube is an acrylic syringe with removable face plate that allows a specially designed 0.7 L sample bag to be placed inside. The bag is attached to the face plate which is then secured to the syringe. A sample is collected by pulling the plunger, or can be purged by pushing the plunger. The Vac-U-Tube can be used for headspace soil gas sampling.

  • No electronic pump required
  • Quick bag samples - setup takes less than 20 seconds
  • Convenient for testing of monitoring wells
