DOSIFUITE : ready-to-use single-dose fluorescein
The simplest, most accurate and fastest solution for detecting a water leak.
When a leak is suspected—whether on a flat roof, in a swimming pool, inside a pipeline, an EU/EP drainage network, a technical shaft, or even within an industrial installation—the real challenge is not confirming the loss of water. The real challenge is locating the exact origin of the leak.
To address this, Fluotracking developed DOSIFUITE: a ready-to-use single-dose fluorescein solution, instantly operational, stable, highly visible, and precisely concentrated to reveal water pathways within minutes, even when they are completely invisible.
With its compact 100 ml format, precise 0.15 g/L concentration and full compatibility with UV lamps, DOSIFUITE has become a standard among technicians, plumbers, waterproofing contractors, pool specialists and maintenance teams.
What is DOSIFUITE ? Purpose and benefits of fluorescent tracing
DOSIFUITE is a pre-diluted fluorescent tracer based on fluorescein, packaged in a 100 ml bottle and ready for immediate use. Its purpose: to reveal the path of a water leak instantly, accurately and visually—whether inspected with the naked eye or under UV light.
Pre-dosed and pre-diluted
Unlike powders or concentrates requiring preparation, DOSIFUITE needs no prior handling :
- no dosage calculation
- no additional tools
- no dilution
- no possible human error
Ready to use straight after opening.
Controlled concentration: 0.15 g/L
A concentration chosen to ensure :
- optimal visibility
- compatibility with swimming pools
- clean coloration without overdosing
- immediate readability during tracing
Instant reaction under UV light
Fluorescein reacts strongly to UV lamps, providing :
- precise identification
- efficient detection in dark environments
- faster inspection
100 ml format : the ideal unit dose
The 100 ml bottle allows :
- a single, controlled test
- precise application
- zero waste
- easy transport and storage for technicians
Key advantages of DOSIFUITE for professionals and homeowners
1. Fast and unambiguous diagnostics
The fluorescein in DOSIFUITE instantly highlights any defect allowing water circulation—micro-cracks, infiltration points, capillary paths or waterproofing failures. Instead of long elimination processes, the tracer shows exactly where the leak travels.
2. Extremely easy to use
Just three steps: open, pour, observe. No preparation, no extra equipment—minimising errors and saving time on site.
3. Exceptional visibility
DOSIFUITE provides bright yellow-green coloration detectable with the naked eye, and dramatically enhanced under UV. Even when diluted, the tracer remains readable—ideal for complex environments such as pools, drainage networks, technical basins or roofs.
4. Safe, water-soluble and non-corrosive
Its formula is :
- non-corrosive
- fully water-soluble
- biodegradable
- harmless to materials and installations
It is easily flushed away by rinsing or filtration (pools).
Where to use DOSIFUITE ?
Flat roof leak detection
Fluorescein reveals weaknesses in waterproofing membranes, localised infiltrations and micro-capillarity zones that are difficult to identify visually. The coloration progressively reveals the true path of water.
Swimming pools : liner, concrete, fibreglass
Quickly check critical areas: skimmers, lights, drains and pipe penetrations. When poured near a defect, the tracer naturally travels toward the leak—providing a reliable visual indicator, even in deep or large installations.
Drainage networks (EU/EP), shafts, siphons, technical ducts
DOSIFUITE detects :
- leaking joints
- abnormal cross-flows between floors
- infiltrations in technical shafts
Industry and maintenance
Used for hydraulic testing, quality control and leak detection. Its ability to circulate through large volumes without losing visibility makes it ideal for preventive maintenance programmes.
How to use DOSIFUITE : step-by-step guide
1. Preparation
Clean the area if necessary, stabilise the water flow, and prepare a UV lamp for dark environments to maximise visibility.
2. Application
Apply DOSIFUITE directly into water, into a crack, a pipe, or upstream of the suspected leak. The tracer naturally follows the water path.
3. Observation
Monitor the movement and intensity of the coloration. Under UV, the contrast dramatically increases, making the leak easier to pinpoint.
4. Cleaning
Fluorescein evacuates naturally :
- by filtration (pools)
- by rinsing (roofs, networks)
No permanent stains or material alterations.
