Material characteristics of animal serum bottle

Animal serum refers to the light yellow transparent liquid separated from the plasma after the fibrinogen and certain coagulation factors have been removed after blood coagulation or refers to the plasma from which the fibrinogen has been removed. Animal serum bottles that store serum are generally made of polyester (PET). What are the characteristics of this type of material?

PET media bottle

The storage temperature of serum is generally between -5°C and -20°C. The main function is to provide basic nutrients, provide hormones and various growth factors, provide binding proteins, provide contact promotion and growth factors to make cells adhere to the wall and prevent mechanical damage. Cells in culture play a certain protective role. The PET serum bottle has the following characteristics:

1. High transparency and good gloss;

2. Good mechanical properties, impact strength 3-5 times that of other films, and good folding resistance;

3. Resistant to oil, fat, dilute acid, dilute alkali, and most solvents;

4. Good heat aging resistance, the brittleness temperature is -70℃, and it still has a certain degree of toughness at -30℃; PET is not easy to burn, the flame is yellow, and the burning oil drips;

5. Non-toxic, tasteless, good hygiene and safety, and can be directly used for food packaging;

6. The permeability of gas and water vapor is low, and it has excellent gas, water, oil and peculiar smell performance.

The excellent characteristics of PET material fully meet the storage requirements of serum. This animal serum bottle can also be used for long-term storage of aqueous solutions, such as culture media, pancreatin, reagents, etc.
