Homogenizer Beads and Tubes
Artikelnummer: D1031-01
The efficiency of bead homogenization relies on several factors, including the material and size of the beads. Benchmark offers a variety of bead options to meet a wide range of samples.
Silica (glass) homogenizer beads are ready to use – acid-washed and heat treated to remove contaminants and render them nuclease and protease-free.
Triple-Pure™ Zirconium Homogenizer beads are ready to use and certified nuclease and protease-free. The tubes are filled in a process that is tested by qPCR to be free of stray DNA. (6mm satellites are acid washed and heat treated, but not certified.)
Steel beads are much denser than zirconium and are useful for the homogenization of harder samples as well as dry grinding. Beads are alcohol-washed, and heat treated to remove contaminants and render them nuclease-free.
