ASI Instruments introduced the revolutionary Monkey Brain Matrix that set new standards in durability and performance among tissue dissection aids. It was a triumph of “Imagineering”; a problem solved by approaching the challenge with the curiosity of a scientist, the ingenuity of an inventor, and the logic of an engineer.

All of our Large Brain Matrices are the highest quality instruments currently available. These units are a must for the discriminating scientist. We truly have the largest selection of matrices on the planet. ASI Instruments coined the product name, the name that has become the standard in labs around the world, Monkey Brain Matrix. Today we have enlarged our line of Large Brain Matrices to include the Dog Brain Matrix as well as the Cat Brain Matrix.

These units are cast in High Grade Zinc using the Actual Animal Brain for unsurpassed cavity definition. You can chill them, sterilize them, subject them to rigorous daily use and still afford them.

Our Matrices have a Patented Self-Cleaning Slot Design for easy maintenance and clean-ability.  Once again raising the bar in instrument design.

“The Best Anywhere” say scientists who are quickly obtaining repeatable sections as small as 2mm, day after day, year after year, even from lab to lab and at chilled temperatures.

Our engineering staff will work with you to develop Custom Matrices to meet your specific lab needs.
