SPECTRALON® FLUORESCENCE STANDARDS
FEATURES:
- Consistent, Reproducible Fluorescence Reflectance
- Highly Diffuse
- Environmentally Stable
- Rugged, Long Lasting
APPLICATIONS:
- Calibration of Colorimeters and Spectrofluorometers
- Standards for the Biomedical, Pharmaceutical and Textile industries
- Paper Industry Standards for Reflectance of "Bright White" Paper Products
Download Guide 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 photochemically stable, compared to their organic counterparts. The stability of the inorganic fluors, when combined with the durability of the Spectralon®, results in rugged, long-lasting fluorescence standards for both field and laboratory use.
Labsphere's Fluorescence Standards are sold individually, in sets of three identical fluors, or as a set of the five fluors described. Each standard is housed in a durable delrin holder with a protective cover and is uncalibrated.
