SSUV300 In Vitro Sunscreen Spectrophotometer

  • SSUV300 Sunscreen Spectrophotometer
  • SSUV300 sunscreen analyser
  • PMMA plate carrier

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.
