PERFORMANCE

High NA and large surface detection: for the best sensitivity in very low fluorescence concentrations.
High throughput detection: 100 kHz acquisition allows the detection of fast events.
Custom geometry of the detection area: 6 reticules selectable with features from 200 µm to 2 mm to fit most requirements.
Continuous acquisition or pulse mode for point measurement: pulse from 50 µs to 10 s.
High sensitivity: Fluorescence detection limit: < 20 pW full bandwidth.
Compact size: A fluorescence detection system that fits in a shoe box.
Easy interactivity: FluoReader can interact with other Elveflow products through the Elveflow software suite.
