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 lung, trachea, 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 Lung / Tracheal Tissue Homogenization in the Bullet Blender™
The protocol described in this document is for the use of the Bullet Blender™ for the homogenization of pulmonary (lung) or tracheal tissue (from a variety of animals). Note that the time and speed settings may differ due to the variation in consistency/texture of tissue 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:
pulmonary or tracheal tissue, Bullet Blender™, homogenization buffer, pipettor, microcentrifuge tubes, and 0.9-2.0mm stainless steel bead blend (part number SSB14B).
Instructions:
- Cut lung or tracheal tissue tissue into appropriately sized pieces for analysis (50mg-300mg) and place into a microcentrifuge tube. Typical sample size: 200mg – about¼ of a rat lung.
- OPTIONAL: Wash tissue 3x with ~1mL PBS. Aspirate. NOTE: This step removesexternal contaminants (blood, etc.).
- Add stainless steel beads (0.9-2.0mm). Use a mass of beads equal to 3x your mass of tissue. One scoop of beads ≈ 220mg.
- Add 0.1mL to 0.6mL buffer (2 volumes of buffer for every mass of tissue).
- 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 twominutes at the SPEED 8.
- 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.
Bullet Blender™ 50 Homogenization Protocol for Lung
The protocol described in this document is for the use of the Bullet Blender™ 50 for the
homogenization of Lung / Pulmonary Tissue. 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:
lung , Bullet Blender™ 50, homogenization buffer, pipettor,
50mL centrifuge tubes, 4.8mm stainless steel beads (part
number SSB05).
Instructions:
- Cut lung into appropriately sized pieces for analysis (0.1g – 3g) and place into a
50mL centrifuge tube.
- OPTIONAL: If desired, wash the tissue 3x with 5mL PBS to remove blood and
mucus from the tissue.
- Add three times as much 4.8mm stainless steel beads (by mass) as you have
sample (so for 1g sample, add 3g beads). Each bead is 457mg.
- Add five volumes of buffer per mass of tissue (5mL of buffer per gram of tissue)
- Tightly screw the centrifuge tubes closed.
- Place tubes into the Bullet Blender™ 50.
- Set controls for SPEED 8 and TIME 5 minutes. Press start.
- After the run, remove the tubes from the instrument.
- Visually inspect samples, if homogenization is unsatisfactory, run for another five
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.
