No Cross Contamination
The samples are homogenized (or mixed) non-invasively. The
sample tubes are kept closed during agitation, as the
samples are processed. There are no probes to
clean between samples.

Samples Stay
Cool
The instrument uses very
little power due to the unique, patented design.
It uses a small DC motor to agitate the individual
tubes, not ultrasonics. Also, because
the motor does not need to agitate any heavy
platforms or plates, it is small and will last for
years.
>
Convenient to Use
Simply place your skin and other tissue samples or cell cultures and some beads in standard
high quality polypropylene tubes, and load the tubes into the
Bullet Blender™. Set the duration (typically a few
minutes) and speed (vigorousness). There are no probes to clean.
And it is quieter than a sonicator and does not heat up
your samples more than a few degrees!

Risk Free Purchase
The Bullet Blender™
comes with a 30-day money back guarantee and a two year
warranty, with a three year warranty on the motor. The simple, reliable design enables the
Bullet Blenders™ to
sell for a fraction of the price of ultrasonic or
other agitation based instruments, yet provides an easier,
quicker technique.
> Established Protocols
Protocol for Epithelial Tissue Homogenization in the Bullet Blender™
The protocol described in this document is for the use of the Bullet Blender™ for the homogenization of epithelial tissue (from a variety of animals). Note that the time and speed settings may differ due to the variation in consistency/texture of various types of epithelial tissue, and variations from species to species. This protocol does not specify a particular buffer-- you may choose which is most appropriate for your downstream application (nucleic acid isolation, protein extraction, etc.).
Materials Required:
epithelial tissue, saline, Bullet Blender™, homogenization buffer, pipettor, microcentrifuge tubes, and 0.5mm zirconium silicate beads (part number ZSB05).
Instructions:
- Cut tissue into appropriately sized pieces for analysis (5mg-300mg) and place into a
microcentrifuge tube. If possible, use long, thin pieces.
- OPTIONAL: Wash tissue 3x with ~1mL PBS. Aspirate. NOTE: This step removes
external contaminants (blood, etc.).
- Add zirconium silicate beads (0.5mm) to the tube. Use a mass of beads equal
to 1.5x your mass of tissue.
One scoop of beads ≈ 192mg.
- Add 0.025mL to 0.6mL buffer (2 volumes of buffer for every volume of cells,
minimum of 25μL).
- Close the microcentrifuge tubes.
- Place tubes into the Bullet Blender™.
- Set controls for SPEED 8 and TIME 5 minutes. Press Start.
- After the run, remove tubes from the instrument.
- Visually inspect samples. If homogenization is unsatisfactory, run for another two
minutes at SPEED 10.
- Proceed with your downstream application.
SAFETY NOTE!!!
When using a centrifuge to separate your homogenate from
the debris and beads, make sure your tubes are balanced.
