Plasma
The gel at the bottom of SST tubes is a gel separator made of a material like silicone. Its purpose is to separate the serum (liquid portion of blood) from the clot (solid portion of blood) after the blood has been centrifuged. This makes it easier to obtain a clear serum sample for testing.
Blood serum can be obtained by collecting a blood sample from a vein and allowing it to clot. The sample is then centrifuged to separate the serum from the rest of the blood components. Serum is the liquid component of blood obtained after clotting, which does not contain cells or clotting factors.
A laboratory test where venous blood is clotted in a test tube is called a serum clotting test. Once the blood sample clots, it is centrifuged to separate the liquid portion (serum) from the clot, which can then be used for various diagnostic tests.
The componants of blood are as follows:plasma makes up 55-60% of whole blood. (plasma would be the clear liquid potion of blood)red cells or erythrocytes makes up 40-45% of blood volumewhite cells (leucocytes) include granulocytes and monocytes making up about 1% of blood volume.
To obtain serum, the coagulated blood is left to clot at room temperature for approximately 15 to 30 minutes. After it is completely clotted, it is rimmed using an applicator stick and then centrifuged for approximately 5-10minutes at 2500 revolutions per minute. Then the supernatant fluid is separated.

Your question is unclear - the liquid which carries red and white blood cells and platelets is blood. These cells are the solid component of blood, which separates from the liquid part (plasma) when centrifuged.

The liquid organ of the circulatory system is blood. The liquid portion of the blood, minus the formed elements, is the plasma.

The liquid that comes out of a burn is Plasma. It is the clear, yellowish fluid portion of blood in which cells are suspended. It is your body's healing fluid.
When a tube of blood is centrifuged, erythrocytes end up on the bottom of the tube.
The liquid portion of a clotted specimen is called serum. Serum is the clear, yellowish fluid that separates from clotted blood after coagulation. It contains water, electrolytes, antibodies, and other substances.
Blood is what a chemist would describe as an aqueous solution; the liquid part is simply water.
Serum is the liquid portion of blood AFTER it has clot. Compared to plasma, which is the liquid portion of blood before it clots. The difference is the absence of fibrinogen in serum.
Blood Serum is the liquid portion of a blood clot.
