Wet Surface Pen

Writes on Wet Surfaces, Under Water & at Any Angle

Versatile ‘space pen’ writes clearly on wet, greasy and other hard to mark surfaces. Use it under water, upside down and in the harshest of temperatures.

• Excellent for marking slots on Southern, Northern and Western blots or for marking alignment dots on blotting filters placed over agar plates containing bacterial colonies or phage plaques
• Mark lanes on wet blots prior to cutting the filter into strips to be incubated separately with different antisera or probes
• Correct or write on wet labels that were kept in a water bath, in liquid nitrogen or in a freezer at -20 °C (-4 °F)
• Extremely useful for marking filters during processing underwater-based buffers
• Handy and reliable for writing on vertical surfaces including the Economy Write-on™ Label Tape Dispenser (F13473-0000) and Wall Mount Adapter (F13473-0001)
• Writes on dry paper as a standard ballpoint pen
