Pass the dust wipe, first try.

A field tool for RRP-certified renovators and abatement crews. See lead-paint dust on the surface before the wipe sample goes to the lab. Clean what you can see. Pass clearance.

Individual lead-based paint dust particles glowing green under 365 nm UV after Fluoro-Spec.

EPA dropped the dust hazard standard 87.5%.

Any detectable lead in dust is now a hazard. The on-site toolkit has not kept up. Wipes go to a lab and come back days later. RRP clearance is a subjective cleaning-verification card. Crews finish the job, the lab fails them, they come back to re-clean.

Fluoro-Spec puts the detection on the surface, in real time. One drop of the reagent. A 365 nm UV penlight. Lead-paint dust glows green. Everything else stays dark.

Ron's crew. Ten passes in a row.

Ron Pike picked up a Fluoro-Spec kit at the 2024 National Lead and Healthy Homes Conference. First job out, his crew passed ten inspections in a row, first time using it. Then they ran out. The next dust wipe failed. He ordered about $300 of Fluoro-Spec the next day.

Seeing individual particles of lead-based paint dust is exceedingly valuable, especially now that EPA dropped the dust hazard standard 87.5%. Ron Pike

The bench data.

Ritter (2025). Single-Particle Detection of Lead-Based Paint Dust via Field-Deployable Methylammonium Bromide Fluorescence. Independent bench work at Spirochaete Research Labs, East Setauket, NY.

38 LBP particles

Individual lead-based paint particles, XRF-confirmed, from a pre-1978 home.

100% visible fluorescence

Every LBP particle ≥ 40 µm fluoresced visibly to the naked eye under MABr + 365 nm UV.

0 false positives

Nine non-lead paint controls. Zero false positives at any size, in any condition.

From the notes: "All LBP particles ≥ 40 µm fluoresced visibly to the naked eye upon contact with MABr and 365 nm UV light, with no false positives observed in the non-lead group."

Who this is for.

  • RRP-certified renovators who eat the cost of failed clearance.
  • Abatement contractors finishing pre-1978 housing work.
  • Public-health and HUD grantee staff training contractor cohorts.
  • Facilities and property management running in-house turnover.
  • Inspectors and risk assessors who want a field check between samples.

What you use.

One Fluoro-Spec FS-1D kit. About 500 lead-dust-particle chances per bottle. 365 nm UV reader included. Made in New York at Spirochaete Research Labs. Refillable.
