Can I leave a Vapor Pin® sampling device in place between sampling events?

Yes. The Vapor Pin® sampling device can stay in place as long as necessary. For repeated use, we recommend a flush mount installation using a stainless steel Vapor Pin® sampling device to protect the pin from damage and corrosion. Keep in mind that the flush mount cap is not watertight and should not remain in place in areas subject to contaminant spills. If future sampling is not required, the Vapor Pin® sampling device should be removed and the hole in the slab filled with hydraulic cement.
