SarstedtMarkers - Blue (10 per Pack)

We use these markers in our research lab and they are great for permanent marking on surfaces. We're able to write on tubes that go into the freezer and on plates that go into the incubators and the marker holds up to the elements. We've been using these for years and love them!

I have tried quite a few and these are the best for marking on most surfaces and the don't wash off unless you take alcohol to them.

I work in a lab and these are marvelous. I haven’t come access anything they won’t write on. The first marker has lasted me 6 months. They are worth the money.

Love these markers. The fine point allows me to easily write on blood tubes. I also use them for writing on glass tubes in the laboratory. The ink stays on We'll through a centrifuge and a lot of handling.

Good but expensive

Really like err Them but you have To be careful what paper u write on, ink sinks thru

I refuse to use Sharpies after having using Sarstedt markers. I do a lot of microscope work where I have to mark petri plates and Sarstedt markers work even at and angle. The tip does not frey and get mushed easily. I've used the blue and green and both colors stay dark even after drying.

These markers are, by far, the best for marking on solid surfaces. I have these in black and blue and both work great. The ink in Sarstedt markers stays dark even after it dries, unlike Sharpie fine point markers. And they hold up to more wear on tube tops than sharpies. These markers are my go-to for writing on tubes going in the freezer or the incubator. Can't get a better lab marker!
