Excellent markers!

These markers are truly alcohol and water resistant! Things I've discovered about these markers:

- Ink dissolves in mineral oil and glycerol
- Easy to read with a range of temperatures; I've used it to label autoclave containers, tested it in a 37C water bath, in liquid nitrogen and dry ice
- The pens may explode and cause an uncleanable spill on the floor and down your lab coat
- The ink flows easily and is always easy to read; won't fade as long as you let it dry

I followed some tips from other reviewers that I think are important:
- Keep the pens upright when not in use
- From time to time dab the tip with a wipe to keep it clear and unclogged
- Vent the tip occasionally; I think this could potentially help prevent spills/leaks

Some features that could be implemented/improved:
- Attached caps/caps with clips
- Finer lines. Not sure if it's possible with the way the ink flows out
- Reusable pens with ink refills
- All black or all red packs. Other colors?

I will definitely keep using these pens! Highly recommend if you're ok with a higher maintenance pen

PCR (Pipette Cry Repeat) every day all day

We do clinical PCR and clean everything with 3% hydrogen peroxide or dilute sodium hydroxide to get rid of DNA and RNases. We also freeze thousands of samples. The markers work well for labeling reagents that come into contact with the cleaners, and the ink also withstands freezing. The moister that condenses on the tubes and containers does not bother the ink at all. I don't have to worry about labels coming off of ink smearing when handling reagents. I wish the tip were finer. The marker tends to bleed, so the writing is thicker than the tip. But the markers are still better than any other marker we have been using. Thank you.

THEY LAST A LONG TIME

Relative to other lab markers I have used, these markers rock! Most lab markers are pretty bad in my 20-year experience: they both dry out and come off. I've been using my black marker consistently for about three months. The marker still seems like it has plenty of ink in it. My VWR marker would have dried out by now. Further, our VWR lab markers do not write on paper very well because the tip is very dry. But these engineering markers can write on both paper and plastic.
