Labsphere’s UV-2000s transmittance analyzer benchtop R&D system is designed to rapidly measure the spectral transmittance of sunscreen products, especially those with high protection factors SPF 50 and above, as well as UVA/UVB protection factor.; The instrument measures the diffuse transmittance of a product sample over the 250 nm – 450 nm ultraviolet wavelength range.; Its application software automatically converts measurement data to provide the Sun Protective Factor (SPF), UVA to UVB ratio, critical wavelength, Boot Star Rating, and UVA-PF (COLIPA Method).; The platform allows users to view, archive, retrieve and export data for measurements on both bare substrates and product substrates and supports evolving regional methods with subscription-based updates.
