I'm looking for a source of inert colored beads which I can use to
visualize the small agarose plugs which we use to purify genomic DNA.  Any
size or color is OK, as long as they are biocompatible and reasonably
inert, e.g., agarose, polystyrene, etc.  Any suggestions would be
welcomed.  Thanks for your help.
