PAP Pens

PAP PEN LIQUID BLOCKER Super Pap Pen
This newest generation of Pap Pens is still a superior hydrophobic liquid, which creates a secure boundary on glass and plastic around a tissue specimen during IHC procedures. Redesigned in 2001 for in-situ methods and stronger adherance. Fluid flows as a light blue on the slide and is easier to see than original (clear) pap pens.
