PAP GnomePen Flat Liquid Blocker

The GnomePen Flat Liquid Blocker has the same great GnomePen Classic Liquid Blocker features but generates a wide hydrophobic line to accommodate thick slices and Z-stack confocal microscopy.  It forms a thin layer that does not interfere with cover slip application.  It is optimized for tissue sections between 10-60 microns thick.  Estimated coverage would be for approximately 250 slides.

Use of the GnomePen Flat:

1. 1. 1. Make sure glass surface is dry. If possible, apply before starting your assay.
      2. Shake the pen thoroughly (10-20 seconds) before use. If the pen was stored under 25°C, unscrew clockwise and re-screw before use.
      3. Clean the GnomePen tip.  Use a kimwipe or soft paper wipe to clean the tip before starting.
      4. Hold the white tip of the pen and push the (clean) steel tip of the pen against the glass.
      5. Move quickly and draw a continuous line around your sample.
      6. Raise the pen off the surface once done.
      7. If a thicker line is needed or flow doesn’t begin instantly, gently squeeze the clear pen body.
      8. Allow pen line to fully dry before starting.  Drying time is about 30 seconds in chemical fume hood (recommended) or 60 seconds on the bench.
