The SPF-290S is a recording UV-VIS spectrophotometer designed and optimized for the determination of SPF values on a variety of sunscreen and cosmetic products, reducing the need (and cost!) for in vivo testing.

Covering both the UVB and UVA regions, the system automatically scans from 290 to 400 nm, accumulating and storing data at 5 nm intervals. The monochromatic protection factor (MPF) is determined for each of the 23 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.

Multiple locations can be scanned on a single sample, reducing operator's sample preparation time and improving accuracy.
