The high-powered Bullet Blender® STORM 5 enables you to homogenize, disrupt, or lyse up to 12 tissue or cell culture samples (up to one gram per sample) at a time in standard 5 ml tubes. Load the samples into the tubes, place them in the Bullet Blender, set the time and speed and you're ready! The "bullets" in the instrument vigorously strike all of the tubes and homogenize your sample in minutes.

The "STORM" model of the Bullet Blender has extra power to improve the homogenization of tougher samples and also incorporates air cooling to dissipate heat.  The air cooling draws circulates ambient air into the Bullet Blender, maintaining samples at ambient temperature.  (Tip: Place a Bullet Blender STORM in a cold room to keep samples near 4°C!)

Bullet Blender STORM 5 accommodates 5ml skirted screw-cap Axygen tubes.

    Consistent Results

    The more powerful Bullet Blender 5 allows homogenization of larger samples than the original Bullet Blender and prepares up to 12 samples in just minutes. All of the samples are automatically homogenized in the same manner to minimize sample-to-sample variability.

    No Cross-Contamination or Sample Loss

    There are no probes or blades to cause cross contamination or sample loss, which also means there are no parts to clean between runs. The sample tubes are kept closed and self-contained during homogenization.

    Samples Stay Cool

    The instrument uses very little power due to the unique, patented design, so there is very little heat build up in the instrument or inside the sample tubes, and a cooling fan helps keep samples very close to ambient temperature. It uses a DC motor to agitate the individual tubes.  The Bullet Blender is designed for reliability and durability, with few moving parts and a very low rate of motor wear.

    Easy To Use

    Simply place your sample, beads and buffer in standard tubes, and load the tubes into the Bullet Blender. Tune the extent of disruption by adjusting the run time and speed. Afterwards, place the sample tubes in a centrifuge to separate the lysate. No special holders are needed. There are no clamp plates nor locking rings to fiddle with.

    What is the RPM range of the Bullet Blender Storm 5?

    Next Advance does not disclose the RPM specifications for the Bullet Blenders. The reason they do this is because the mechanism of action for the Bullet Blenders (striking) is very different from the mechanism of action for other laboratory bead mill homogenizers, which almost exclusively act via shaking. Direct comparisons with different bead mills from different manufacturers based on RPMs, including using protocols from other instruments based on RPM, are not possible.

    The best we can tell you is that the speed setting "1" is a speed which would be good for a moderately vigorous mixing, and the maximum speed is the most power you will get from the instrument. The specific RPMs which correspond to the numbers on the dial are not documented by Next Advance.
