MOGorilla is right about contacting Fisher or VWR for tubes...
The best part is, you'll also get to choose the type of "additive" inside the tubes -- EDTA for a preservative, stuff to make blood clot, serum-separator tubes, etc. And wait until you see the wide selection of colors for the tops! (Each has its own meaning) :shock:
So, just be sure to get "plain" tubes (no additives). :wink:
Better yet, check with a Doc or nurse in your area to see if you can get some "out of date" tubes from their supplies inventory. They will have to dispose of outdated tubes per some internal policy, but you might offer to do that for them. It's worth a call...
