CC'n some heads

So my glass burette was broken YEARS ago. This involved falling cats, running dogs, beer, and high explosives. It was one hell of a mess.

And then I discovered THESE:

At only 5 bucks each, and only a couple bucks for locally bought syringes, they look attractive.

Now I cannot tell for certain if they are calibrated below tens of CCs but I can easily do that with a syringe. All that needs to be accurate is the area between about 60 and 75, so that should not be much of a trick. What do the rest of 'ya do?
