Got a pack of Corning 3574 assay plates here. These are the 384-well version with the non-binding surface and flat bottoms. They're white polystyrene, non-sterile, and come in a pack of 10. The outer packaging is still sealed but just a heads up the expiration date on the label says 2012, so keep that in mind for your lab work. Great if you need some extra plates for testing or non-critical stuff.
