In brief: IV bag
Blood is collected by IV into a specialized, sealed, sterile plastic bag containing an anti-coagulant.
It is then refrigerated (after blood typing and testing for infections) until needed. The shelf life is 21-35 days depending on the preservative used (anti-coagulant).

Some blood products may be preserved for one year like frozen plasma. Others like platelets have a shelf life of only 5 days at room temperature and in constant agitation. Some places have Red cells preserved for 42 days with some additive solutions and refrigerated.
In brief: About half a liter
Usually a whole blood collection is about 500 milliliters or half a liter. This is approximately 10% of a person's total blood volume, our body can handle this process without major side effects.
Every healthy person that weight more than 110 lb and has 17 years of age or more is a potential blood donor, just visit the closest blood drive and save a live in just 10 mins.
