PAP Pen MaxTagâ„¢ Histo for IHC - - 1 Each

PAP PEN is intended to provide a hydrophobic barrier when a circle is drawn around a specimen on the glass slide. Before use, hold the pen point up and press it with fingertip to take blocked air out from the pen barrel to prevent overflow. To start, press the tip of the pen straight down until fluid starts soaking the tip and then draw the circle around the specimen. Be sure to close the cap after use. Perform the dyeing work after the ink has dried well. If too much ink comes out, wipe it off.
