quantiFlash® is a precise LED based light source that is ideal for instrument independent quality control in flow cytometry. It enables the user to calibrate the intensity scale of each channel in a flow cytometer to a meaningful absolute unit which is “number of detected photo electrons”. Now a direct quantitative comparison between different devices and different manufacturers becomes possible. Using a calibrated intensity scale makes it easier to transfer a measurement from one flow cytometer to another and it improves the comparability of the results obtained from different flow cytometers.

quantiFlash® provide two light channels. One delivers fixed amplitude light pulses for triggering and the other one light pulses with variable amplitude to characterize the flow cytometer. The variable amplitude light pulses are controlled to within 0.1% of their set amplitude, outperforming all currently available calibration particles by far. They have a dynamic range of over 4 decades and can be precisely tuned. To extend the dynamic range even further a separate 20 dB optical attenuator is available.
 

quantiFlash® was developed in cooperation with J. C. S. Wood, Wake Forest University, Comprehensive Cancer Center Flow Cytometry Core Facility and Deutsches Rheuma-Forschungszentrum Berlin.
