About Vapor Pin®

Cox-Colvin & Associates, Inc. has developed 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 patented design reduces the potential for leaks during sample collection, improving sample quality
  • Built-in disposable seal eliminates the need for grout, increasing productivity
  • Connects easily to sampling equipment
  • Easily installed, sampled, and retrieved for reuse
  • Reduces damage to the slab
  • Improves diagnostic testing
  • Improves spatial resolution
  • 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. Protected under US Patent # 8,220,347 B2, US 9,291,531 B2
