Some things one learns when one is NEN half day busy figure out what is actually in these small 2ml plastic tubes is that froze anyone in the last 5 years
-. Permanent Marker are not permanent, something to label it in plastic and then frozen and thawed several times and then freeze the font does not look good.
This is especially for all colored pencils, black will last longer.
- Normal household sticker not hold when it freezes for some time at -80 ° C. But they fall off until the water is what it is stuck to the plastic tubes to thaw. This is bad, especially if it happens somewhere where NEN breeze, and we no longer know which sticker was one that plastic tube.
- you put his head for 30 seconds or longer in a freezer, then this has the same effect as when one eats his ice cream too fast.
- E5 or E WT is not a sufficient label for a plastic tube. Especially not if you do not write to find out exactly the explanation for that name is in the lab book and left the institution three years ago.
