Blood-spinning is a medical procedure used to shorten the healing time of an injury. Small samples of the patient's blood are taken and spun in a centrifuge , allowing platelets and blood serum to be isolated from other blood components.
The machine spins the red cells in a circular bag and then uses a hydraulic system to express out saline, plasma, glycerol used in the freezing process, and unwanted plasma proteins. The blood is washed in a special, single-use washing kit with a circular bag and five tubing lines branching from a central tube from the circular bag.
Ultracentrifuges spin the rotors under vacuum, eliminating air resistance and enabling exact temperature control. Zonal rotors and continuous flow systems are capable of handing bulk and larger sample volumes, respectively, in a laboratory-scale instrument. [1] Whole blood is often separated, using a centrifuge, into components for storage and ...
Continuous flow centrifugation (CFC) historically required two venipunctures as "continuous" means the blood is collected, spun, and returned simultaneously. Newer systems can use a single venipuncture by pooling blood in a vessel and cycling through drawing and returning blood though the needle while the centrifuge continuously processes blood remaining in the vessel.

A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed.There are various types of centrifuges, depending on the size and the sample capacity.

The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.
