The SSUV300 boasts numerous advantages in the performance of accurate measurement of UV absorbance of thin film sunscreen samples.
Including a dual monochromator based spectrophotometer, a simple magnetic PMMA plate carrier and integrating sphere, collection of transmitted light and accurate measurements in accordance with international standards is ensured.
The challenging measurement of sunscreen products, including high absorbance, fluorescing samples and diffuse transmission properties are fully taken account of in the design of the SSUV300.
