• Listed bead sizes are median (average) values.  Because beads are sorted by sieves, bead size varies between +/-10% of a listed value.

We also offer PRELOADED beads in 2ml screw cap vials.  There are too many possible combinations of bead size, bead composition and bead load to consider stocking all prefilled vials, so we do this on a custom basis.  Let us know what you need at info@biospec.com and we will give you a price quote.
