• Listed bead sizes are median (average) values.  Because beads are sorted by sieves, bead size varies between +/-10% of a listed value.
• With either stainless steel or chrome steel beads, common polypropylene microvials will break if 'dry' grinding or cryo-grinding is attempted in our MiniBeadbeaters.  In this case, our 2 ml stainless steel microvials with silicone rubber caps or our 2 ml XXTuff polypropylene screw cap microvials are recommended.

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.
