The purpose of this administrative supplement request is to acquire “Equipment items to enhance operations at the BioCAT Facility at the Advanced Photon Source”. These items were identified as required to meet unmet needs by our users that were not anticipated in the parent P30 proposal. These include a fluorescence microscopy system, a Wyatt Eclipse system for Flow Field Fractionation, a Newport Hexapod motors for Compound Refractive Lenses and a Nanodrop OneC Microvolume UV-Vis Spectrophotometer.
