Various Bead materials for different sample types
Glass Beads are used for grinding delicate material and the homogenization of soft tissue and easy-to-lyse cell suspensions. Borosilicate glass beads are stronger than Soda Lime glass beads.

Zirconia Silica beads can be used for bead milling of spores and homogenization of medium-soft samples. Zirconia Yttria beads are stronger and ideal for metal-free pharmaceutical and food processing grinding.

Chrome beads are ideal where a through-hardened steel ball is needed, such as grinding leaves and seeds. Stainless Steel are recommended for grinding tough material that may not contain metal traces


  • All glass beads are lead-free
  • Ceramic beads denser than glass and suitable for grinding tough tissue
  • Zirconia Silica ideal for bead milling of spores and the homogenization of medium-soft samples
  • Zirconia Yttria chemically inert and resistant to fragmentation
  • SAE 304 Stainless Steel does not rust and can withstand lysis buffer up to 7 days
  • Beads of consistent high quality for a low bulk price
