Verification

A certificate that survives being forwarded

Screenshots can be edited. A Resolux certificate carries a certificate number, a QR code and a document fingerprint that resolve to a public record showing whether it is current, superseded or revoked.

QR + public URL

Scan or paste the certificate number to check authenticity in seconds.

Versioned, never overwritten

Corrections issue a new version; the prior one is marked superseded.

Privacy preserving

Verification shows result integrity — never your billing or contact data.

Chromatograms included

Purity results ship with the trace and integration detail behind them.
