How can the blood plasma be separeted from the cellular component of the blood?

Answer 1

Blood is separated by centrifugation. That's like when you spin a bucket round your head and it stays put which is centrifugal force. Well, blood is spun round and the heavier particles, red blood cells, go to the outside, middle platelets stay in the middle and the lighter plasma is balanced on the top. Centrifugal force comes from the Latin meaning Centrum "center" and fugere "to flee". It is made when the substance is spun and pushed to the outside; the particles that are heavier have more gravitational pull so they are pulled to the bottom of the container they are in. The machine that blood is separated in is called the centrifuge they are used in laboratories and on an industrial scale for separating solids in suspensions of liquids.

Answer 2

Whole blood, a sample in a tube or donor blood in a bag, is centrifuged to separate the blood. The actual separation is done either by aliquotting with a pipette for testing or by a sterile method of "squeezing" the bag so the supernatant (plasma) travels through a tube to a satellite bag before it's sealed.

Answer 3

Spin it in a centrifuge and the blood will seperate with the most dense part (Red blood cells) at the bottom, the least dense (plasma) at the top with a buffy coat (white blood cells and platelets) in the middle. Approximately 45% is RBC's, and 55% is plasma with less than 1% being the buffy coat.
