Depends on what kind of tube/test you are performing?
10-15 min usually. 20 min on rare tests.
No you do not centrifuge blood for a CBC. This could cause issues when reading the results.
its depend on the test and centrifugal machines.
Centrifuge.
Blood can be separated by centrifuge based on the different densities of its components. When spun in a centrifuge, the heavier components such as red blood cells are forced to the bottom of the tube, while the lighter components such as plasma rise to the top. This allows for easy separation of the different parts of the blood for various analyses or procedures.
To separate plasma from blood using a centrifuge, the blood sample is first collected in a tube. The tube is then placed in the centrifuge and spun at high speeds, causing the blood components to separate based on their density. Plasma, being the lightest component, will rise to the top of the tube, allowing it to be easily pipetted off and collected for further analysis.
By using a centrifuge
You spin it in a centrifuge.
You use a centrifuge. This is a machine which spins the sample of blood round. This causes the different substances to separate. Hence, the plasma will separate from the blood cells (which are heavier).
Spinning it in a centrifuge will separate the blood cells from the plasma.
practically, separating plasma in the blood is through the use of a centrifuge. it is a fast rotating instrument that causes the settling down of heavier blood subconstituents at the bottom part of the blood sample.
To centrifuge a red tube you will have to run the blood through and then put it back into the body. The red tube is used to collect plasma.
A serofuge is a small centrifuge specifically designed to separate serum from cells and to complete blood cell washing procedures. Like a centrifuge, a serofuge has holes to insert the centrifuge tubes in, a lid to protect both the samples and experimenter in case of malfunction, and a way to set the centrifuge speed and way to turn the centrifuge on and off.
