Vapor Pin® Sampling Devices are manufactured with a female thread at the bottom specifically for attaching a barbed adapter, available on the Vapor Pin® website. The barbed adapter allows you to attach tubing to the bottom of the Vapor Pin® Sampling Device to increase sample depth, to add a particulate filter such as an aquarium bubbler, etc. The barbed adapter has the same size barb as on the top of the Vapor Pin® Sampling Device and fits the same tubing.
You can also increase the sample depth with the Vapor Pin® Extension, which also screws into the bottom of the Vapor Pin® Sampling Device. The extension has male threads at the top and female threads at the bottom, allowing you to screw them together to extend the sample depth as much as desired in 1.5-inch increments.
Vapor Pin® has developed a particulate filter that can be screwed directly to the bottom of the Vapor Pin® Sampling Device. This device is called the Vapor Pin® Filter.
The Vapor Pin® Sampling Device and its accessories are evolving rapidly to keep pace with customer needs. Please feel free to call us to discuss the latest developments, cost, and availability.
