The Invitrogen™ Qubit™ Flex Fluorometer is a high-performance benchtop fluorescence quantification instrument designed for precise and sensitive measurement of DNA, RNA, microRNA, protein, and endotoxin. Engineered for higher throughput and improved reproducibility, the Qubit Flex Fluorometer enables simultaneous quantification of up to eight samples, significantly reducing assay time and variability compared to single-sample fluorometers.
Using highly selective fluorescence-based detection with Qubit assay kits, the Qubit Flex system provides superior accuracy compared to traditional UV absorbance methods. Its intuitive touchscreen interface, built-in calculators, and flexible data export options make it an essential tool for genomics laboratories, sequencing facilities, and molecular biology research environments.
