INQUIRY

The SPF-290AS is a UV spectrophotometer designed and optimized for the determination of sun protection values (SPF UVA, Critical Wavelength, etc.)on a variety of sunscreens and cosmetic products.

Covering both UVB and UVA spectral regions, the system automatically scans from 290 to 400 nm, accumulating and storing data at intervals of 1,2 or 5 nm. The monochromatic protection factor (mPF)is determined for each of the selected wavelengths and is used to calculate solar protection values using solar irradiance curves and biological action spectra programmed into the software(but which can be easily modified).

Sunscreen Protection Factor Analyzer Features

Fully automated multi-point sampling
Two modes of automated operation
Intuitive software features
Validation Kit Included
High correlation with in-vivo testing
