It`s easy to use, eliminates cross-contamination and speeds up sampling. You know the routine: Drop it in. Pull it out. Drop it in. Pull it out. Drop it in. Pull it out. And so on. Well now there is an easier way: The SingleSample® Bailer Retrieval System. The Bailer Retrieval System features a 7" reel with free-spin preventer that makes bailing and sampling faster and easier. And the prewound, disposable twine eliminates cross-contamination. A Well Head Bracket is also available to support the reel and bailer while purging and during sample removal through the bottom valve. Twine is provided on 4" cores in 100, 200 or 300 foot lengths.
