Stainless steel beads can be cleaned and reused.
A more economic and time-saving option is to used chrome steel beads. These beads are much less expensive than stainless beads. Consequently, they can be used once and discarded.
With either stainless steel or chrome steel beads, common polypropylene microvials will break if 'dry' grinding or cryo-grinding is attempted. Our stainless steel microvials with silicone rubber caps or our XXTuff polypropylene vials are recommended for this application.
