The high-powered Bullet Blender STORM enables you to homogenize, disrupt, or lyse up to 24 small (300 mg or less) tissue or cell culture samples at a time. Load the samples into 1.5 ml polypropylene microcentrifuge tubes, then place them in the Bullet Blender. The "bullets" in the instrument vigorously strike all of the tubes and homogenize even very tough samples 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!) The new STORM Pro replaces the analog controls with a touchscreen.

Consistent Results

The Bullet Blender STORM prepares up to 24 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 STORM 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.

Risk Free Purchase

All Bullet Blenders include a 30 day money back guarantee and a 2 year warranty.

What is the RPM range of the Bullet Blender Storm?

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.

If you have questions pertaining to the processing power of the Bullet Blender Storm, please contact us for more information.


Can I use the Bullet Blender Storm in a 4°C cold room or inside a 4°C refrigerator?

Yes, you can. If you do so, it is recommended that it "live" in the 4°C space. If that is not possible, do not run the Bullet Blender soon after removing it from the cold space, as condensation may naturally occur on cold surfaces, including the interior electronics. Failures due to condensation or water damage are not covered under warranty.
