The National Institutes of Health (NIH) intends to award a firm-fixed-price purchase order to Cytiva Global Life Sciences for an Ultraviolet Monitor Detector Upgrade for an existing Cytiva AKTA Pure 25 Chromatography System. The required detector must provide simultaneous three-wavelength ultraviolet detection for RNA and protein samples and be fully compatible with the existing system’s hardware, software, data acquisition, and control functions. The Government considers Cytiva the only known source capable of meeting these technical and compatibility requirements, but will consider capability statements from interested parties that can demonstrate they meet all stated requirements. This notice is not a request for competitive quotations. Award is anticipated approximately five calendar days after the notice closes, unless another capable source is identified.
