Now a Cytometer for LARGE Particles!

Union Biometrica, Inc., is the pioneer in the design, manufacture and distribution of COPAS™ Large Particle Flow Cytometers.

These instruments can analyze, sort and dispense objects that are too large (20-1,500 micron) or too delicate for traditional flow cytometers. Typical samples range from small multicellular model organisms (C.elegans, D.melanogaster, Zebrafish) to delicate large cells / cell clusters (adipocytes, embryoid bodies, pancreatic islets, duct cells, hepatocytes), to seeds (Arabidopsis) and beads (cells growing in or on beads, combi-chem libraries, bead based assays).

Samples are analyzed one by one in a continuously flowing stream and each object is analyzed and sorted based on size, optical density and up to three fluorescent parameters. Examples of applications include rapid dispensing into micro-titer plates for assay preparation, population enrichment prior to further experiments, isolation of rare events, and quantification of fluorescence levels of each object.
