Solar Light’s In Vitro Sunscreen Protection Factor (SPF) Analyzer, SPF-290AS, determines the SPF values of sunscreen and cosmetic products, as well as the Ultraviolet Protection Factor (UPF) of sun protecting fabrics. Covering both the UVB and UVA spectral regions, the system automatically scans from 290 to 400nm. The monochromatic protection factor (MPF) is determined for each of the selected wavelengths, and the SPF value is calculated using user-programmable solar irradiance and erythemal constants. The SPF-290AS can reduce the need for time consuming and costly in-vivo SPF testing. As the leading supplier to global SPF testing laboratories and cosmetic manufacturers, Solar Light and its SPF-290AS are recognized for unparalleled quality and reliability.
