How does the serum separating gel separate blood components?

    The serum separating gel is a kind of viscous fluid, which is mainly composed of high polymer and has physiological inertia. In its structure, it contains a large number of hydrogen bonds. The association of hydrogen bonds forms a network structure, and because the polymer is a mixture, polymerized from a variety of monomers with different relative molecular weights, it has a large relative molecular weight, so it will show a uniform gel shape in appearance.
