Vapor Pin™
Cox-Colvin & Associates, Inc. is proud to introduce the Vapor Pin™, a unique, patented, re-usable sub-slab soil-gas sampling device. Traditional sub-slab soil-gas sampling methods are time consuming, expensive, and prone to leaks. Cox-Colvin designed the Vapor Pin™ specifically to eliminate many of the problems associated with traditional sub-slab soil gas sampling methods. Advantages of the Vapor Pin™ over traditional methods include:
- unique design reduces the potential for leaks during sample collection, improving sample quality;
- built-in seal eliminates the need for grout;
- connects easily to sampling equipment;
- easily installed and sampled within same day (can be sampled within 20 minutes of installation);
- easily retrieved;
- reduces damage to the slab;
- reusable/sustainable;
- reduces sampling time allowing collection of more samples for less cost, and thus provides a better understanding of site conditions.
The patented design of the Vapor Pin™ provides environmental professionals a means of collecting high-quality, low-cost soil gas samples within minutes. Plus, the Vapor Pin™ is made in the USA.
