Material characteristics of media bottles

 Serum refers to the pale yellow transparent liquid separated from plasma after fibrinogen and some coagulation factors are removed from plasma after blood coagulation, or plasma from which fibrinogen has been removed. Media bottles for storing serum are generally made of polyester (PET) material. What are the characteristics of this material?

The storage temperature of serum is generally -5 °C to -20 °C, and its main functions are to provide basic nutrients, hormones and various growth factors, binding proteins, contact-promoting and growth factors to protect cells from mechanical damage, Cells in culture provide some protection. The media bottle made of PET has the following characteristics:

1. High transparency and good gloss;

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

3. Oil resistance, fat resistance, dilute acid, dilute alkali, and most solvents;

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

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

6. The gas and water vapor permeability is low, and it has excellent gas barrier, water, oil and odor properties.

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

Material features of PETG media bottles

图片
  PETG media bottles   are a special packaging for storing various media, reagents, serum and other solutions, and it is also a product that scientific researchers have more contact with. The wide range of applications is mainly due to the superior properties of its materials. PETG is a transparent plastic that belongs to the non-crystalline copolyester. Serum needs to be stored in a low temperature environment. The use range of this material is -80°C to 60°C, which makes PETG media bottles fully meet the storage needs of serum. In addition, it has the following features: 1. High transparency, the light transmittance reaches 90%, which can reach the transparency of plexiglass; 2. It has stronger rigidity and hardness, excellent scratch resistance, impact resistance and toughness, which is close to or even exceeds that of polycarbonate (PC), and is suitable for injection molding, extrusion molding and extrusion blowing processing; 3. In terms of chemical resistance, oil resistance, weat

What are the common specifications of serum bottles

图片
  In biological laboratories, we often have to store various solutions and reagents. Thanks to the advantages of good performance, transparency, and temperature resistance, serum bottles have become "frequent visitors" in the laboratory. As a commonly used storage container, what are its common specifications?                      FuDau 60ml-Square-PETG-PET-Media-Bottles Common materials for serum bottles include PETG and PET, both of which have very good temperature resistance and transparency. In comparison, bottles made of PETG have more advantages in terms of barrier properties. If you want to pursue a better storage state of the solution, it is recommended to use a bottle made of PETG. There is a molded scale on the body of the bottle, we can clearly observe the capacity and state of the solution. The common specifications of this kind of container include 5ml/10ml/30ml/60ml/125ml/250ml/500ml/1000ml, etc., which are mostly used to store serum, culture medium, buffer, dis

Cell factory requirements for production raw materials

图片
Cell factories   are mainly used for large-scale cell culture. Cells have high requirements on the environment, such as temperature, humidity, osmotic pressure, pH value, etc. Therefore, this kind of   cell   consumables also has high requirements on raw materials. The first is transparency. In the process of cell culture, it is necessary to grasp the growth state of the cells at any time, and make corresponding adjustments according to the cell proliferation. Therefore, the raw materials of the cell factory must meet the requirements of transparency, so that it is convenient for researchers to observe the growth of cells. The second is the compatibility of materials. The raw materials of this consumable generally meet the requirements of USP Class VI medical polymer materials. Medical polymer materials refer to polymer materials used to manufacture human internal organs, external organs, pharmaceutical dosage forms and medical devices, and their sources include natural biopolymer mate
