To simplify quality assurance and UVA protection factor analysis in the development and testing of sunscreen and cosmetics using Labsphere’s UV-2000S transmittance analyzer, the company has introduced the UV2000S, a sample preparation starter kit. It includes all tools needed to prepare the appropriate in vitro sunscreen sample common to Boot Star, Colipa, FDA and user-defined sun protection factor (SPF) measurement methods. The kit includes a tube of Vaseline, a positive displacement pipette, pipette capillaries and pistons (25 µl), pipette capillaries (100 µl), nonpowdered finger cots and a sample preparation guide. The benchtop R&D system rapidly measures the spectral transmission of sunscreen products, especially those with SPF factors of 50 and above, as well as UVA/UVB protection factor. It measures the diffuse transmittance of a product sample over the 250- to 450-nm ultraviolet range.
