Labsphere Upgrades UV Transmittance Analysis with UV-2000S

To keep pace with demanding industry methods for quality assurance and UVA Protection Factor (UVA-PF) analysis in the formulation, development and testing of sunscreen products, Labsphere has introduced its next generation UV Transmittance Analyzer
(PresseBox) (Wessling, ) Designed to rapidly measure the spectral transmittance of sunscreen products, especially those with high protection factors SPF 50 and above, the UV-2000S builds on the platform of Labsphere’s industry standard UV-1000S with increased dynamic range and functionality.

The rugged bench top instrument quickly measures the diffuse transmittance of a product sample over the 280 nm – 410 nm wavelength range. A dual beam spectrometer with diffuse illumination accommodates accurate measurement of highly scattering samples. No filters are needed to prevent sample overexposure.

The 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. The software is structured to support evolving regional methods for analyzing product UVA Protection Factor (e.g., revised Boot Star, PA+ Method, UVAI/UV Ratio, etc.), meeting foreseeable changes and challenges in the dynamic sun protection industry.

With accurate in-vitro measurement of SPF and UVA-PF, the UV-2000S can greatly reduce the need for expensive in-vivo testing protocols, such as UVA-PF based on Persistent Pigment Darkening. The unit’s sample positioning stage, with user defined sample patterns, enables fast positioning with the accuracy required by approved and proposed UVA-PF test methods. The RoHS compliant instrument meets corporate environmental mandates on hazardous substances.
