Rodent Brain Matrices
WPI offers one of the largest selections of 
brain matrices available. Made of acrylic, 
or stainless steel, these matrices are sturdy 
and can be heated, chilled, autoclaved 
(stainless steel only), scrubbed -- and 
stand up to rigorous daily use. Coronal 
matrices have the additional feature of a 
mid-line sagittal cut to facilitate splitting 
of the left and right hemispheres. Sections 
can be as fine as 1-mm. The olfactory/
spinal/notch is cut into each matrix.

The small animal guillotine has been completely 
redesigned for ease of use and extra added 
safety features. The blades are drawn together 
by magnetic force to ensure a clean and precise 
cut through very strong bones and skin.
There is a large base for stability, long handle for 
extra leverage, spring action so the blades can 
not fall down unexpectedly, hardened stainless 
blades for endurance, simplified construction for 
easy maintenance. The fluoropolymer coated 
surface on the base makes cleaning easy.
 The guillotine is considered one of the most 
humane methods to sacrifice a subject.
