MFR - MICROFLUIDIC FLUORESCENCE READER
Fluorescence detection for microfluidic device : The FluoReader is a LED Induced Fluorescence (LEDIF) measuring system designed for microfluidic applications. Faster, more sensitive and less expensive than most optical microscopes, it is a smart alternative for real time optical measurement of medium-scale objects (mm scale).
It offers a cost effective alternative compared with high Numerical Aperture, low magnification objective epifluorescence microscopes.
The FluoReader quantifies fluorescence in an area of 2 mm diameter with very high sensitivity and high time resolution. The geometry of the detection area can be tuned thanks to various reticles selectable through a rotating wheel.
This allows to detect fluorescent objects in a circle, a square, a series of stripes or any other geometry of the wanted size.
The fluorescent measurement can be performed either in a continuous mode or in a pulse mode to avoid sample degradation.
- 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.
