Acid Washed Beads by OPS Diagnostics

Acid washing also removes potentially deleterious heavy metals adsorbed to the surface of the bead. The beads are washed with diluted acid, beads are oven dried and baked, at which time they are suitable for most applications. Silica beads are suitable for general grinding applications while zirconium beads have greater density and thus higher

BioSpec Products • Cleaning or Sterilizing Your Beads

Place the beads in a sterile, shallow stainless or glass tray, cover them with paper towels, and air-dry overnight at RT. Store the clean, dry beads in a sealed bottle. If you are isolating nucleic acids from disrupted cells, an easy alternate cleaning method is to immerse the beads in a 1:10 dilution of ordinary household bleach (Clorox or

Silica Based Methods NEB

Silica-based nucleic acid purification methods employ a simple bind-wash-elute process. Nucleic acids bind to the silica membrane in the presence of chaotropic salts. Polysaccharides and proteins do not bind well to the column and residual traces are removed during alcohol-based wash steps, along with the salts. After binding and washing
