Applications
- Fluorescent Tracer For Industrial Water Systems: Added at very low dose to cooling towers, boilers and closed loops, it fluoresces strongly under ultraviolet light so operators can follow concentration, dilution and cycling behaviour and control dosing of fluorescent tagged treatment polymers.
- Inert Tracer For Membrane And Filtration Monitoring: Used as a fluorescent inert tracer in reverse osmosis, ultrafiltration and nanofiltration monitoring, where tracking its passage across a membrane train reveals leaks, integrity loss and cross contamination without interfering with the separation process.
- Water Tracing And Leak Detection Dye: Dissolves readily and is detected by fluorescence under ultraviolet light, making it suitable for tracing water flow, locating leaks and infiltration in piping networks, and for hydrological, environmental and wastewater monitoring studies.
- Fluorescent Probe For Sensing And Materials Research: Its responsive emission makes it a probe in sensor development, including pH dependent detection schemes, and it anchors onto two dimensional materials and polymers through aromatic pi stacking for membrane, adsorption and interaction studies.
- Hydrophilic Fluorescent Label For Bioanalysis: Water soluble and non volatile, it serves as a hydrophilic fluorescent label and cell tracer in imaging and bioanalytical workflows, and it is applied in biosensor composite films and in analytical detection methods.
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
Packaging
Export-grade packaging, custom labels
Solids (woven bags/cardboard drums/ton bags)
Liquids (plastic drums/IBC/ISO tanks)
