How is the Vapor Pin® sampling device better than existing methods for sub-slab vapor sampling?

The Vapor Pin® sampling device is superior to other sub-slab vapor sampling methods because: 1) it’s constructed of a single piece of metal, eliminating potential leak points; 2) it’s installed in minutes using common hand tools; 3) it uses a silicone sleeve to form an air-tight seal between the Vapor Pin® sampling device and the side of the borehole, eliminating the need for grout or other adhesives; and 4) unlike other sampling devices, it’s easily retrieved for reuse.
