Answer #1

Generally blood collected is stored in bags made of PVC. There are majorly two reasons that are responsible for the selection of PVC bags. They are

1. Maintaining platelets concentration by storing the blood in high gas permeability bags. PVC has great permeability towards gases.

2.The stored blood should not get contaminated by the storing medium i.e, bags. PVC is highly inert and doesn't contaminate the blood stored in it.

These major two reasons are responsible for selection of PVC bags for Blood storing.
