Serum is a special substance that refers to the light yellow transparent liquid separated from the plasma after the coagulation of blood after the removal of fibrinogen and some coagulation factors or to the plasma that has been removed from the fibrinogen, providing it with essential nutrients in cell culture. So how should serum be stored and what are the characteristics of serum bottles ?

The composition and content of serum vary with the sex, age, physiological condition and nutritional condition of the animal. Serum contains a variety of plasma proteins, peptides, fats, carbohydrates, growth factors, hormones, inorganic substances, etc., these substances to promote cell growth or inhibit growth activity is to achieve physiological balance. Serum should generally be kept at -5℃ to -20℃. If stored at 4℃, do not exceed one month. If it is not possible to use one bottle at a time, it is recommended to place the sterile subpackaged serum in an appropriate sterilized container and return it to freezing.

Because of the need to be stored in low temperature environment, so the serum bottle must have good low temperature resistance. At present, the bottles on the market mainly choose glass or polyester raw materials. These two kinds of raw material performance is similar, the difference is that polyester raw material bottle is not easy to break, before filling without washing bottle, drying and other processes, reduce production costs, has become the mainstream choice in the market.

The serum bottle of polyester raw material has good low temperature resistance, is not easy to break, square design, easy to grasp, can also be used to store a variety of medium, buffer, cell freeze solution and other solutions.
