To begin plasmapheresis, whole blood will be taken from your arm. The whole blood is then drawn by the automated machine into a centrifuge that spins, causing the plasma to separate from the red blood cells.
As long as 30 days. It will last longer in glass containers and in the refrigerator or a dark place but can be stored in plastic bottles because the alkaline water will not leach like R.O. or distilled water.
Note: The ideal pH level of alkaline ionized water for long term human consumption is between 8.5 and 9.5 (and no greater than 10.0) with the ideal ORP value around -200mV to -300mV (and in no way significantly greater than -400mV).
