Molecular biology grade
beads are cleaned with acidified water to remove fine particulates and
contaminating trace materials, baked to destroy contaminating enzymes,
and then packaged aseptically into sterile media bottles.
Available in both silica (soda lime) and zirconium oxide in five
sizes. Molecular biology grade beads are ready to use for homogenizing
samples for molecular analysis. Silica beads are suitable for
general grinding applications while zirconium beads have greater
density and thus higher impact power.
Recommend size applications:
100 μm - Bacteria, sonication additive
200 μm - Bacteria, small yeasts (e.g., Pichia)
400 μm - Yeasts (Saccharomyces)
800 μm - Molds, pollen |
