Spectralon fluorescence standards aid in the development of optically brightened materials such as paper and textiles and are widely used in the cosmetic industry. Unlike disposable paper fluorescence standards, Labsphere fluorescence standards provide highly stable, reproducible fluorescence reflectance over a long period of time in varying conditions.

Spectralon provides the ideal matrix for inorganic fluors which are photolytically stable compared to their organic counterparts. The stability of inorganic fluors, when combined with the durability of Spectralon, results in rugged, long-lasting fluorescence standards for both field and laboratory use.

Labsphere welcomes inquiries for the development of custom fluorescence standards. For more information contact our Technical Sales Department.

Specifications and Ordering Information

Fluorescence standards are sold individually, in sets of three identical fluors, or as a set of five fluors described. Flourescence standards are uncalibrated. Each standard is housed in a durable delrin holder with a protective cover.
