Ink bleed test

Which pens are best for using in laboratory notebooks? I wrote "123" with inks from a sampling of pens I had, then subjected strips to a variety of abuses (erasing, water, boiling water, methanol, ethanol, acetone) then glued them all back in their positions to facilitate comparison. Some sucked. I was relieved to see that my favorite pen, Zebra Sarasa Blue/Black did well, as did the entire line of Gelly Rolls, which I also love.
