Lumi Flex Fluo - "the Specialist"

Standalone camera system for fluorescence lateral flow test detection.

europium-stained antibodies

powerful 365 nm illumination unit

also compatible with other fluorescent dyes

The Lumi Flex Fluo is a standalone  camera based detection system for lateral flow tests using europium stained antibodies.

Chelated europium complexes can be reliably detected with its superior optical system containing a powerful 365nm illumination unit optimized for reduced shadowing on the objects surface. Pictures are taken with a powerful camera with cut-off filter rejecting light below 600nm. This makes the platform suitable for europium but also other similar fluorescent dyes like Quantum dots.

A second illumination source outside the UV range enables barcode detection on test cassettes for clear identification and orientation check.
