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.
