- Adopting advanced semiconductor chips MARLOW, with a new generation of semiconductor temperature rise and fall technology,
- Adopting T-OpticalTM top detection technology, suitable for white tubes, shielding background interference, improving fluorescence signal sensitivity and signal-to-noise ratio
- Synchronous fluorescence detection for same channel to reduce delay errors.
- Innovative optical design – SSLPTM short path static fluorescence CCD imaging technology, more stable fluorescence signal, higher sensitivity. (Non-fiber optic technology to avoid well blockage. Non-well-by-well scanning technology to avoid heating, wear, and deviation of optical components due to movement, etc.)
- Maintenance-free long-life LED light source, no need to regularly replace or recalibrate the dye.
- 12-row temperature gradient functions
- Langji’s “Optimal qPCR Design Analysis Software”, instrument and analysis results can be remotely controlled. Free upgrade of analysis software for the whole lifetime.
