When stainless steel is impractical and zirconium oxide unnecessary, 4 mm Acid Washed Silica Beads are a good choice for standard laboratory applications. The 4 mm Acid Washed Silica Beads are large glass beads that can be used in conjunction with smaller zirconium and silica beads to form mixed matrix disruption tubes.  The 4 mm Acid Washed Silica Beads are used to homogenize duckweed and its associated bacteria to isolate their DNA including double-stranded RNA (dsRNA) from blue crab samples. These beads are also used for yeast protein extraction, digestion, and phosphopeptide enrichment. Another unique application of 4 mm Acid Washed Silica Beads is to serve as a model for implantable devices to study the effectiveness of the crystallized drug formulations in preventing fibrosis in animals such as rodents and primates.

Silica beads are more economical than zirconium silicates and oxides, while often as effective. Acid-washed silica beads are treated with acidified water to remove fine particles, dust, and other impurities typically found in untreated beads.  They are further baked to drive off organic impurities.
