Do not reuse...

Not worth the risk... you'd need an autoclave to be 100% sure it's clean, and soaking it in alcohol isn't perfect... plus it kills the rubber gasket in the plunger.

Besides have you ever tried to push down the plunger on a 5 or 10cc with a 23g or 25g pin? Not ideal...

Just get a big box of 3cc's. It's like $14can for a box of 100 here. My 2 cents only of course...
