For Microdissection of Frozen Brain Sections
This set of 5 punches (57401) or set of 3 punches (57402), with spring loaded nylon expellers, and a convenient handle, facilitates the “Palkovits Punch” technique of dissecting out specific brain nuclei for neurochemistry.
The nuclei are punched from frozen brain sections on glass slides, and expelled into the reagents. The spring-loaded expellers avoid risk of contamination that might be caused by expelling with breath.
Each punch has an electropolished sharp end for smooth cuts and minimal tissue adhesion. Punch sizes are 0.25, 0.50, 0.75, 1.0, 1.25, 1.50, 1.75 and 2.00 (±5%, slight variation due to electropolish etching to sharpen). The smaller tubes are reinforced by an outer layer of concentric tubing except at the tip.
Replacement punches available individually.
