Model 405 NAPL Flute
Visualize the Source: High-Resolution NAPL Mapping with Solinst Flute
Identify, map, and measure pure-phase LNAPL and DNAPL with surgical precision.
When characterizing a contaminated site, “presence” isn’t enough—you need location. Knowing exactly where pure-phase product is hiding in fractures or pore spaces is the difference between a successful remediation strategy and a costly failure. The Solinst NAPL Flute turns the invisible into a visual map, providing indisputable evidence of free product distribution.
Unlike electronic sensors that provide a “point” reading or dissolved-phase sampling that only suggests a source, the NAPL Flute creates a permanent, visual record of the entire borehole. By using a hydrophobic reactive cover, it ignores water and dissolved contaminants to wick only pure product, leaving a measurable stain exactly where the contamination exists.
Strategic Benefits for Site Characterization
- Direct Visual Evidence: See exactly where NAPL is entering the borehole. The multi-colored dye stripes dissolve on contact with pure product, providing a clear, depth-discrete map.
- Stop the Guesswork: Identify thin layers of LNAPL or sinking DNAPL that traditional interface meters might miss or “smear” across the water column.
- Hydrophobic Accuracy: The specialized cover wicks only pure-phase contaminants, ensuring your data isn’t skewed by dissolved-phase concentrations.
- Zero Cross-Contamination: Built on the Flute Blank Liner technology, the NAPL Flute seals the borehole as it everts, preventing the spread of pure product to clean zones during the test.
- Remediation Ready: Use the visual map to perfectly place sampling ports for Discrete Interval Samplers or to design targeted injection programs for maximum ROI.

Features of the Model 405 NAPL Flute
- Reactive Cover Technology: High-resolution wicking material that reacts instantly to hydrocarbons and chlorinated solvents.
- Rapid Deployment: The liner only needs to remain in the borehole for a short duration to capture a complete profile of the NAPL distribution.
- Removable & Remediable: After the visual map is recorded, the liner is removed, leaving the borehole clean and available for permanent monitoring or remediation.
- Scalable Diameter & Depth: Custom-fabricated for boreholes ranging from 2″ up to 19″ in diameter, with depth capabilities reaching 425 m (1,400 ft).
- Dual-Phase Integration: Can be combined with FACT (Flute Activated Carbon Technique) to map both pure-phase and dissolved-phase contaminants in a single event.
Map the Entire Plume
The NAPL Flute is an integral part of the Solinst Flute characterization suite. Once the pure-phase “source” is mapped, you can seamlessly transition to:
- FACT Profiling to map the dissolved phase.
- Water Flute installation for long-term, multi-level monitoring of the plume’s evolution.
All while using Solinst Flute flexible liner technology that seals the borehole and prevents cross-contamination.
