Brain Punches Collect Precise Volume Tissue Samples w/

The Brain Punch Tissue Set is used for the Palkovits Punch technique, which allows extraction of minute amounts of brain tissue from exact locations in the brain. A hypodermic  tube with a sharp rim is pressed onto a frozen section on a glass slide. The tissue under the hole is freed and pulls away with the punch. It can then be expelled from the punch with the spring-loaded expeller by pressing the top of the punch.

The Brain Punch Tissue Set comes with five color coded punches with spring-loaded nylon expellers, and an aluminum handle. The handle is curved and tapered to minimize visual obstruction and offers perpendicular maximum punch pressure.
