Introduction of serum collection tubes
Serum separation gel is a viscous fluid with a large number of hydrogen bonds in its structure, which form a network structure due to the association of hydrogen bonds. Under the action of centrifugal force, the network is broken down and becomes a low viscosity fluid. When the centrifugal force disappears, it reforms into a network. Return to a high viscosity fluid. This property is known as thixotropy. Using this property, a kind of serum separating glue can be made. When centrifuged in the same tube as the coagulated blood, the gel forms a gelatinous barrier between the serum and the clot. Thus, the recovery rate of serum was improved, serum was preserved in the original state, clinical examination process was simplified, and work efficiency was improved.
Properties of Serum Separatio Coagulant
The composition of serum gel is inactive to blood, and has no influence on clinical chemistry and immunoassay. The concentration of anti-jolt drugs in 12 kinds of blood was detected by four kinds of separated glue vessels. The results showed that the concentration of anti-jolt drugs decreased after several days of serum storage because of the different materials of plastic tubes. The reason for this is not the separation glue but the hydrophobic compounds contained in the treatment drugs that attach to the plastic wall.
Serum separation gel is a viscous fluid with a large number of hydrogen bonds in its structure, which form a network structure due to the association of hydrogen bonds. Under the action of centrifugal force, the network structure is destroyed and becomes a low viscosity fluid. When the centrifugal force disappears, it forms a network again and returns to a high viscosity fluid. This property is called thixotropy. Using this property, a kind of serum separating glue can be made.
