100 µm Acid Washed Silica Beads, 200 gm 

One of the original glass beads used for beating, 100 µm Silica Beads are small, yet dense enough to mechanically disrupt bacterial cell walls, or in combination with larger beads, disrupt fungi and plant cells. Comparable to Lysing Matrix B, these glass beads are effective for disrupting bacteria by bead beating for nucleic acid (genomic DNA and RNA) and protein extractions.  The 100 micron glass beads are useful for homogenizing bacterial cultures or disrupting microbes from environmental samples.  Bead beating with glass beads can be done in 2 ml homogenization tubes up to vials and small jars.  Silica beads are acid washed and baked to both remove contaminants and destroy nucleases and proteases.  The bulk (bottle) packaging is an economical alternative to pre-filled tubes.
