How would you separate the solids from blood?

Centrifugation

Centrifugation is the most commonly used method to separate the solids from blood. It involves spinning the blood sample at high speed in a centrifuge, which causes the heavier solid components to settle at the bottom of the tube while the lighter liquid components remain at the top. The solid components, which include red blood cells, white blood cells, and platelets, can then be easily separated from the liquid component, which is plasma.

Filtration

Filtration can also be used to separate the solids from blood. This method involves passing the blood sample through a filter paper or membrane with pores that are small enough to trap the solid components while allowing the liquid components to pass through. The solid components, which include red blood cells, white blood cells, and platelets, can then be collected on the filter paper or membrane, while the liquid component, which is plasma, can be collected in a separate container.

Precipitation

Precipitation is another method that can be used to separate the solids from blood. This method involves adding a chemical reagent to the blood sample, which causes the solid components to precipitate out of solution. The solid components, which include red blood cells, white blood cells, and platelets, can then be collected by centrifugation or filtration, while the liquid component, which is plasma, can be collected in a separate container.
