Lab marker pens
Posted 20 November 2012 - 06:10 AM
I'm looking for the perfect permanent marker which is alcohol-resistant and writes on all surfaces. I find that most "permanent" markers come off easily after a good 80% ethanol (v/v) wipe down especially in tissue/cell culture work where you sterilise everything by ethanol. I also had trouble when sterilising aliquots which were labelled by supposedly "permanent" markers.

Colleagues use it on daily basis in tissue culture lab, where they wipe even more carefully and don't report any problems, obviously you shouldn't scrub it that much
It's very hard to get off glassware, but it's acetone based, so you can wipe it out easily with acetone.
I never trust anything that can't be doubted.
