The science behind separating blood and platelets OneBlood

The science behind separating blood and platelets OneBlood

A machine called a centrifuge spins your blood to separate your red blood cells, platelets and plasma. As the blood is separated, the heavier reds cells sink to the bottom and are given back to you. The liquid plasma rises and in between these two components is a layer of platelets that are tracked into a small pouch wrapped around the cylinder ...

RCF Centrifugation and RPM Centrifugation

Dec 31, 2021 RPM is a measure of how fast the rotor spins and while this information can be useful but it does not have the ability to determine the amount of g the sample is exposed to. A centrifuge running at 5000 RPM for instance, would be spinning at 5000 RPM regardless of the type of centrifuge employed and the dimensions of the rotating rotor.

How to convert Centrifuge RPM to RCF or G-force? - Clinfield

Jul 15, 2012 The answer is easier than you think…. The force exerted on a particle in a centrifuge is a simple function of the rotation speed of the centrifuge and the radius of rotation. The actual equation is: RCF or G-force= 1.12 x R x (RPM/1000). R is the radius of rotation measured in millimetres. For example in the photograph below R is 240mm.

How fast can you spin a human in a centrifuge?

Oct 27, 2011 It came up in conversation “ how fast could you spin a human in a centrifuge? ”. According to my friend Sophie, a person can survive up to 9 g at constant rotation. The average width of a person is 22 inches, so a ‘rotor’ width of 50 inches would accommodate a person. This adds up to 80 rpm in a person-sized centrifuge.
