Happy New Year’s to you and yours!

2024 marks the 40th anniversary of the original Rodent Brain Matrix!
In 1984, we introduced the original, market first, Rodent Brain Matrix. A product that has, over the last 40 years, has completely changed scientific research. Through the years our original Rodent Brain Matrix designs have been the fixture in many of the world’s top universities in countries around the world, both in research and in academia itself. Also, many of the top U.S and overseas companies use and have used our brain matrices to assess and develop theories, new products, and life-changing medicines for people all around the world. 

We are the true original rodent brain matrix and the are best on the market still, with unmatched versatility, cavity definition and slice repeatability. Other competitors may try to imitate our original design through inferior materials, rushed machining, or even just a cheap and, virtually research unviable, 3D printing a piece of material with zero defined cavity.

Moreover, we were also the first to introduce Large Brain Matrices (specifically Monkey, Dog, Cat, Pig) and well as various Tissue Matrices. Like the original Rodent Brain Matrix, these are now often copied all over the world with inferior designs or materials, just compare the brain cavity definition and the slot / material quality to see the undeniable original ASI difference.

40 years of unmatched innovation, 40 years of change, 40 years of making a difference.
