An easy-to-use testing methodology, combined with reproducible results, opens the door to efficient and low cost experimental design techniques for formulation optimization. The SPF-290AS delivers reliable results on the most difficult samples. The high correlation between the SPF-290AS in-vitro measurements and in-vivo test results provides confidence that the analyzer will be a reliable guide to product performance. We also offer 3M™ Transpore™ tape and Transpore tape holders for performing less demanding measurement data collection. Sample holder for 50 x 50 mm PMMA platesĭepending on your intended testing methods, additional boxes of two hundred PMMA plates in either 2μ roughness or 5μ roughness are available optionally.PMMA plates, 50 x 50 mm, 5μ roughness, sample set of 3.10 syringes with tips, 1 ml, disposable.Equipped with this tool, users will not spend time performing tests on an analyzer that is in need of repair, nor will they spend money for repairs that are not necessary. This feature is designed to provide a clear understanding and validation of how your SPF-290AS analyzer is performing against factory measurements for optical density, wavelength accuracy, and correlation to in-vivo testing whenever desired. The Comprehensive Test Plate contains several optical filters that are measured by the SPF-290AS, and the results are compared to NIST-traceable factory measurements. The SPF-290AS is the perfect choice for quick, efficient, and accurate analysis of:Īn SPF-290AS Validation Kit is included with each analyzer and comes complete with a Comprehensive Test Plate. The monochromatic protection factor (MPF) is determined for each of the 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.)

Covering both the UVB and UVA spectral regions, the system automatically scans from 290 to 400 nm, accumulating and storing data at intervals of 1, 2, or 5nm.

This self-contained, attractive desktop unit reduces the need and associated cost for in-vivo testing. Solar Light’s versatile SPF-290AS UV Transmittance / Sunscreen Protection Factor Analyzer is an integrated turnkey UV spectrophotometer, designed and optimized for the determination of SPF values on a variety of sunscreen and cosmetic products, as well as materials testing.
