Photometric and Wavelength Accuracy Reference Materials Kit

The solutions in this secondary standards kit are shipped in a re-usable UV-protective storage container and come with Certificates of Calibration. This kit includes four glass filters mounted in precision aluminum spring mounts. The cells are designed for use with standard 10 mm cuvette holders. Three of the filters are neutral density glass filters for checking spectrometer ordinate accuracy. The fourth filter, holmium oxide, is for checking spectrum wavelength accuracy. These materials require periodic recertification. PerkinElmer offers recertification services (N1010539).
