Description

Technical Field

[0001] The utility model relates to the technical field of serum separation, in particular to a separation device for animal serum. Background Art

[0002] Animal serum refers to the yellowish transparent liquid separated from the plasma after the blood has coagulated, after removing fibrinogen and certain coagulation factors, or refers to the plasma from which the fibrinogen has been removed. Its main functions are to provide basic nutrients, hormones and various growth factors, binding proteins, contact-promoting and growth factors to prevent cell adhesion from mechanical damage, and to play a certain protective role on cells in culture.

[0003] Animal serum is generally separated by a centrifuge. During the centrifugal operation, the test tube containing the blood needs to be fixed inside the centrifuge. The existing fixing method is generally to set a carrier inside the centrifuge, and the carrier is provided with a plurality of through holes that match the diameter of the test tube to be placed. The test tube is directly embedded in the through hole to complete the fixation of the test tube. However, when the diameter of the through hole opened on the carrier is exactly the same as the diameter of the test tube, the stability of the test tube after being placed in is high but the placement is difficult and it is easy to scratch the wall of the test tube. When the through hole diameter is larger than the test tube diameter, the test tube is easy to place but the stability is poor. For this reason, we propose a separation device for animal serum.
