12V Low Flow
Material: Silicone
The Vapor Pin ® was specifically designed to collect soil gas for sub-slab vapor-intrusion assessments. By sampling the soil gas directly beneath the building's floor, the Vapor Pin ® System provides the most accurate risk assessment of vapor-intrusion. Sub-slab gas most closely represents the indoor air contamination without indoor or outdoor air quality factors. The convenience of the close-to-surface location makes sampling from these sites easier to collect using hand-held equipment. The Vapor Pin's compact design makes it possible for a single technician to install and sample. Vapor Pins ® are installed by drilling 5/8-inch holes through the floor with a hammer drill. For Flush mount solutions, the Vapor Pin ® Secure Cover can be installed with a 1-12" hammer drill.
After installing the Vapor Pin ® and allowing soil gas to equilibrate for two hours or more, connect the Summa canister, Tedlar bag, or another sample container to the Vapor Pin ®, purge the dead space in the sample train, and collect the sample.
