Description
The SPEX 2155 SamplePrep Stainless Steel Grinding Ball is a specialized accessory designed for efficient and robust sample homogenization in laboratory settings. This particular grinding ball has a 9.5 mm diameter and is constructed from 440C stainless steel, a material known for its hardness, durability, and resistance to wear, making it suitable for grinding tough samples.
These grinding balls are primarily used in high-throughput tissue homogenizers and cell lysers, such as the SPEX SamplePrep Geno/Grinder and MiniG homogenizers. They function through bead beating, a process that involves vigorous pulverizing motion to disrupt cell membranes and homogenize plant and animal tissues. This enables fast and efficient extraction of nucleic acids, DNA, proteins, and other molecules of interest from various biological matrices. The 9.5 mm size is particularly effective for grinding larger or denser tissue samples, making it versatile for a range of applications, from small tissue biopsies to larger plant samples.
The SPEX 2155 grinding balls are compatible with 24-well microplates and 5 mL vials designed for bead beating. They are autoclavable and reusable, though they can also be discarded after a single use, offering flexibility for laboratory workflows. Their robust construction ensures consistent grinding performance and reliability in demanding sample preparation procedures.
