I assume you mean the little containers that look like a small test tube?
Those are called vacutainers. They hold from about 3-10 ml. Even two sets would only be about 80ml max (usually about 1/2 that but it depends on what they're testing for).
Will that hurt you? It depends on the size of the patient but remember this - the first rule of medicine is do no harm. No doctor or nurse would deliberately draw enough blood to endanger you.
The guy/girl at the blood donation site is giving about a pint. 473ml or almost 6 times what you gave.
