Summary
Solar Light’s versatile SPF-290AS UV Transmittance / Sunscreen Protection Factor Analyzer is an integrated turnkey desktop system for quick, efficient, and accurate UV Transmittance analysis of sunscreens, liquids, lotions, creams, sprays, gels, powders, emulsions, textiles, and more
Solar Light’s versatile SPF-290AS UV Transmittance / Sunscreen Protection Factor Analyzer is an integrated turnkey UV spectrophotometer, designed and optimized for the determination of SPF values on a variety of sunscreen and cosmetic products, as well as materials testing. This self-contained, attractive desktop unit reduces the need and associated cost for in-vivo testing. Covering both the UVB and UVA spectral regions, the system automatically scans from 290 to 400 nm, accumulating and storing data at intervals of 1, 2, or 5nm. The monochromatic protection factor (MPF) is determined for each of the selected wavelengths, and is used to calculate the SPF value, using solar irradiance and erythemal constants that are programmed into the software (but which can be easily modified.)
The SPF-290AS is the perfect choice for quick, efficient, and accurate analysis of:
- Liquids
- Lotions
- Creams
- Sprays
- Gels
- Powders
- Emulsions
- Textiles
