The COPAS FP-250 instrument features our smallest flow cell available (250 µm) and is ideal for use with all stages of C.elegans as well as cell clusters like mouse adipocytes, ESC's / EB's, hepatocytes, pancreatic islets, and duct cells as well as small beads and seeds with sizes from 20 to 200 microns (diameter). Although the FP-500 can also be used for sorting C. elegans, the FP-250's 250µm flow cell is preferable if you need to sort eggs as well as adults. The specially designed fluidic path and small flow cell have been optimized for small objects to provide the highest size resolution measurements while achieving the fastest sort rate. Objects are analyzed and sorted using size, optical density and up to three channels of fluorescence. Objects meeting the sort criteria may be dispensed into 24-, 48- 96- or 384-multiwell plates or bulk receptacles.
