Our Chrome Steel Sample Beads from Luna Nanotech are engineered for the most demanding sample preparation tasks. With an exceptionally high density of 7.9g/cc, these beads provide the intense mechanical force required for effective disruption of extremely tough biological materials such as dry plant tissues, hair, bone, teeth, and seeds.

Key Features:

• Superior Material: Constructed from high-quality chrome steel, offering unparalleled durability and impact for tough sample homogenization.
• High Density Performance: The 7.9g/cc density ensures efficient and complete lysis of even the most fibrous and resilient samples.
• Targeted Sizing for Diverse Applications: Available in a range of diameters, each optimized for specific applications:
  • 1.3 mm beads: While generally smaller, these beads are effective for the fine pulverization of tough, small samples or for achieving a finer particle size after initial disruption with larger beads.
  • 2.3 mm beads: Widely used for disrupting tough fibrous plant materials, such as monocotyledon leaves, and for homogenizing various cryopulverized tough tissues like mouse melanoma and skin for DNA extraction.
  • 3.2 mm beads: Excellent for dry grinding a single seed into a fine powder or for robust hair sample preparation (e.g., 60 mg hair). Also utilized for DNA extraction from plant tissues like spinach leaves.
  • 6.35 mm beads: The largest size, providing maximum impact for pulverizing whole seeds or large, extremely tough samples such as tobacco petioles. Ideal for initial gross tissue disruption.
• Convenient Packaging Options: Supplied in prefilled, self-standing 2 mL or 7 mL screw-on cap tubes for single-use convenience, and 450 g bottles for larger-scale needs.

These chrome steel beads are an indispensable tool for researchers requiring aggressive mechanical lysis for extracting nucleic acids, proteins, and other analytes from samples that resist conventional homogenization methods. Their material properties and size variability ensure optimal results, even with the most challenging biological matrices.
