Filling microfuge tubes with beads is a painful, time
consuming task. Not any more! OPS Diagnostics now offers
pre-filled tubes using our acid washed grinding media. Each tube
contains 325 μl of molecular biology grade beads in a 2 ml screw-cap microfuge
tube. This allows for the homogenization of 650 μl sample,
typically microorganisms, while allowing for the required headspace
for efficient disruption by vortexing or bead beating.*
Tubes are available with silica beads as well as the higher impacting
zirconium beads.
Recommended size applications for Pre-Filled Tubes:
100 μm - Bacteria, sonication additive
200 μm - Bacteria, small yeasts (e.g., Pichia)
400 μm - Yeasts (Saccharomyces)
800 μm - Molds, pollen
Pre-Filled Tubes can be used with the
Pulsing Vortex Mixer,
GenoGrinder, or
HT Homogenizer. |

* Work in our laboratory
determined that the most efficient homogenization of microbes by bead
beating used 1 part beads to 2 parts culture broth. The total
volume of the beads and broth should not exceed half the volume of the
tube. Consequently we fill our tubes with 325
μl of beads so that following the addition of 650 μl
sample, the total volume is just under half the volume of the tube. |
