Model VST Portable Vacuum Samplers

Key Features

  • Versatile Controller.
  • Accurate, Repeatable Sample Volumes.

The VST can be used for a wide range of sampling needs from heavy influent to critical storm water or combined sewer overflow sites. The larger 5/8-inch internal diameter (ID) intake option is recommended for applications with potential clogging problems or large solids. It is ideal for liquids containing hard organic matter, which harmlessly pass through the sample tract and into the bottle, preventing expensive repairs and critical failures. The lightweight VST can be easily transported to remote sites or used at fixed locations.
