The Bullet Blender™ and Bullet Blender™ Blue
Rupture your spleen with ease... or smash, batter, break, beat, grind, homogenize, liquify, smoosh, tear up, ...
(You get the idea. Hopefully,
it's not YOUR spleen...)
Your spleen tissue samples stay cool
during homogenization!



The Bullet Blender™Lyse E. coli and other cells. Homogenize or disrupt tissue. The Bullet Blender is quiet and user friendly.

> No Cross Contamination
> Samples stay cool
> Convenient
> Risk  Free

Homogenize up to 24 spleen samples simultaneously-- in less than 5 minutes!

 

The Bullet Blender™ enables you to homogenize up to 24 samples (spleen or other tissues) in separate microcentrifuge tubes at a time.  Load up to 300mg spleen tissue with your application buffer and grinding beads in standard polypropylene microcentrifuge tubes.  Place the tubes into the Bullet Blender™ (pictured above) or Bullet Blender™ Blue.  The "bullets" in the "blender" vigorously strike all the sample tubes as the instrument runs for a few minutes.  The agitation of the grinding agents with the tissues homogenizes the samples.


The Bullet Blender™ and Bullet Blender™ Blue enable you to disrupt or homogenize up to 24 spleen and other tissue/cell samples at a time.  Load the samples in standard polypropylene microcentrifuge tubes into the Bullet Blender™.  Balls (the "bullets") repeatedly strike the sample tubes in a controlled manner, thousands of times per minutes, inducing vigorous motion of the tissue samples or other substances inside the tubes, providing efficient mixing. With beads in the tubes, the samples are thoroughly homogenized. Tune the extent of disruption by adjusting the speed. Click here to see sample protocols.

> 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 splenic tissue 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.

> Protocol development assistance
We can help you use the Bullet Blender™, if protocols are lacking for your application.  Our Technical Support staff will advise you on setting up your experiment as well as troubleshooting the experiments which didn't turn out like you planned.

Protocol for Splenic (Spleen) Tissue Homogenization in the Bullet Blender™

The protocol described in this document is for the use of the Bullet Blender™ for the homogenization of splenic (spleen) 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:

splenic tissue, Bullet Blender™, homogenization buffer, pipettor, microcentrifuge tubes, and 0.5mm zirconium oxide beads (part number ZrOB05).

Instructions:
  1. Cut spleen tissue into appropriately sized pieces for analysis (50mg-300mg) and place into a microcentrifuge tube. One BALB/c mouse spleen ≅ 100mg.
  2. OPTIONAL: Wash tissue 3x with ~1mL PBS. Aspirate. NOTE: This step removes external contaminants (blood, etc.).
  3. Add zirconium oxide beads (0.5mm). Use a mass of beads equal to 2x your mass of tissue (so for 100mg tissue, use 200mg beads). One scoop of beads ≈ 190mg.

  4. Add 0.1mL to 0.6mL buffer (2 volumes of buffer for every mass of tissue).
  5. Close the microcentrifuge tubes.
  6. Place tubes into the Bullet Blender™.
  7. Set controls for SPEED 8 and TIME 3 minutes. Press Start.
  8. After the run, remove tubes from the instrument.
  9. Visually inspect samples. If homogenization is unsatisfactory, run for another
    10. two minutes at the SPEED 8.
  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.
