Fluorometer adopts the fluorescence detection principle, the sample volume is only 1-20u, with the corresponding quantitative reagents can realize accurate concentration quantification. The fluorometer is an open platform, which can be flexibly adapted to different reagent brands, such as Qubit dDNA quantification kit, SSDNA quantification kit, RNA quantification kit, microRNA quantification kit, etc., as well as other brands of quantification kits adapted to the Qubit “4” device.
