Spectrophotometer SPF-290AS

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 sun protection values, using solar irradiance curves and biological action spectra programmed into the software (but which can be easily modified).

Directions for use

In vitro part

The SPF-290AS spectrophotometer is easy to use, designed and optimized for evaluating the sun protection (UVB and UVA) of cosmetic products….

Firstly, thanks to the integrated software that measures and calculates the various solar protection values.

Last but not least, the optical geometry enables absorbances from 0 to 3.2 Abs to be measured horizontally.
