For an introduction to the application and use of Certified Reference Materials in absorption spectrophotometry

Starna’s universally accepted spectroscopy CRMs, customised for the performance qualification of plate readers. A plate reader adaptor is also available to enable the use of conventional Starna  liquid cell and solid filter references in plate readers.

Sealed Cell Microplate Reference

sealed cell microplate 

Contains six heat-sealed liquid CRMs in a black anodised aluminium microplate. Potassium dichromate solution is used as an absorbance reference, and holmium oxide solution as a wavelength reference.

Filter Microplate Reference 

 UV-Vis - Micro-Plate Reader Liquid Filter Reference Plate

Of identical configuration to the liquid cell microplate references, but contains Starna NIST traceable glass filter CRMs instead of the liquid cells. For absorbance, neutral density filters are used, and holmium glass for wavelength.
